Cars are complicated. Especially engine – it needs to be fed the proper amounts of air, fuel, and spark. The suspension and brakes must be in tip-top shape. The wheels and tires, transmission, cooling system, gauges—even the seats—must all function properly. With all these being really important, many often neglect the importance of the vehicles electrical wiring system.
Poor wiring will keep your electrical components from operating at full potential. Many people would never consider the idea of wiring a vehicle. It can be daunting. — so we’ve put together a few tips to help you understand the basics.
Round Up The Right Tools – Start with a quality set of wire strippers – they will usually include a group of holes to fit most wire gauges. This enables the stripping of the insulation off your wires without accidentally cutting into the wire conductors. A wire cripper is necessary when you install solderless connectors. Most quality crimpers have two or three sections on the nose to fit various lug sizes. You can even get crimpers with wire cutting and wire stripping sections.
A soldering Iron is needed for splicing wires or securing oversized connectors that cannot be crimped. You will need solder designed specifically for electronics and wiring . Here are some other items that should be in your electrical toolbox:
Gauge Your Wiring Needs
A factory wiring harness includes the necessary wiring for standard electrical components like windshield wipers, horn, headlights, etc. However, when you add electrical or electronic components to your vehicle, like high-end audio or racing electronics, you need to choose the proper wire on your own. There are three factors to consider: size, material, and color.
Wire size is measured by gauge—the smaller the gauge number, the larger the wire. The gauge you need depends on the current draw of the accessory and the wire length between the accessory and the power source. In general, the larger the current draw, the larger gauge wire you need to properly power the accessory.
One factor to consider with long lengths of wire is voltage drop. The longer the wire, the greater the voltage drop. You can offset voltage drop by increasing the size of the wire. As a rule of thumb, try to maintain a less than 0.5% voltage drop to assure maximum performance.
Wire material is usually aluminum or copper. For automotive purposes, we recommend stranded copper wire for the greatest flexibility and conductivity.
Wire color may not seem important at first glance, but it becomes crucial when you try to trace a faulty circuit down the road. To keep yourself from tearing your hair out, color-code your wire by accessory. It will help you keep track of which wire goes where during installation and troubleshooting.
Make the Connection
There are two main types of connectors: soldered and solderless. Soldered connectors are necessary with oversized wiring or if you’re splicing wires together. Solderess, or crimp, connectors can be used for most other wiring, and we’d recommend using them wherever possible.
Solderless connectors are the easiest to use and provide a good, strong connection. Usually, solderless connectors come with color-coded insulators, so you know which gauge wire they are designed for. Solderless connectors come in a variety of configurations:
Butt connectors are shaped like cylinders and are ideal for joining two wire ends together. A wire end is inserted into each end of the connector, which is crimped to complete the connection.
Spade connectors are ideal for components that are removed or serviced often. A male connector on one end of the wire fits into a female connector on the other end of the wire, completing the connection. To disconnect, just pull the connectors apart.
Ring connectors are used to secure wire to screw-type terminals; they are secured by the terminal screw.
When installing any type of connector—soldered or solderless—it is a good idea to use shrink tubing. Shrink tubing is relatively easy to install and provides added protection against electrical shorts and outside elements.
Choose the Right Components
There is more to wiring a vehicle than, well, wire. For example, you will need some sort of overload protection to protect your expensive electronics. The three basic types of overload protection are fuses, fusible links, and circuit breakers:
You should also install relays with your wiring if your electrical accessories require a bigger current draw than a standard power switch is rated to handle. And since most switches are designed to work with very limited currents, relays are required just about every time to wire a new aftermarket electrical accessory.
Relays are extremely useful for handling high-amperage electrical accessories like large electric fans, fuel pumps, and HID headlights. They are activated by an electric coil and controlled by a switch. When the relay is closed, no power goes to the accessory in question. When you flip the accessory switch, an electric coil in the relay opens, sending power to the accessory.
There are plenty of other products to make your wiring tasks easier, including switch panels, multi-circuit main and auxiliary fuse blocks, toggle, push-button, and remote-mount switches, and of course, wiring harnesses for everything from fog lights and gauges to complete vehicles.
Map Out a Plan
Before you begin your wiring project, map out a plan. Lay out the wiring or wiring harness so you know where each wire goes and that you have enough wire to complete the job. Locate the fuse box in an easy to reach location like your glove compartment or center console. Place the necessary relays, fusible link, or circuit breakers at connections between your power source and your electrical accessory.
If the wiring isn’t labeled already, label each wire or harness with the name of the components they route to. If the wiring or harness will be going through the firewall, use a grommet in the hole so the sheetmetal won’t cut through the wires. Don’t secure the connectors until the wiring is through the firewall.
Choose a spot on or near the firewall for the common ground point for the harness, and one point for a chassis ground on the negative side of the vehicle. This method gives you a single path to the negative side of the vehicle and provides a more effective ground. Use 10 gauge or bigger wire to connect the common ground to your chassis ground.

Significant gains in battery technology favour electric motors moving into the future. Current electric cars, powered by lithium-ion batteries, can reach ranges of almost of 300 miles on a single charge Tesla fans recently drove a Model S more than 700 miles in one go. Straight away this takes away the more recent questions and concerns around how far you can drive without needing to stop versus a diesel or petrol car.
Many thought leaders actually believe the “total cost of ownership” of an electric car will reach parity with a petrol one next year. Predictions are being made that electric vehicles will make up 14% of global car sales by 2025. Regulations are tightening, too. Last month the UK joined a lengthening list of electric-only countries, saying that all new cars must be zero-emission by 2050.
Electrification has thrown the car industry into potential chaos. Many leading brands are founded on their engineering heritage—especially in Germany. Compared with existing vehicles, electric cars are much simpler and have fewer parts; they are more like computers on wheels. That means they need fewer people to assemble them and fewer subsidiary systems from specialist suppliers.
While today’s carmakers grapple with their costly legacy of old factories and swollen workforces, new entrants will be unencumbered. Premium brands may be able to stand out through styling and handling, but low-margin, mass-market carmakers will have to compete chiefly on cost. Ultimately, what this means is, new competition in the industry from players such as Apple and Google will drive the cost down, and through innovation, the quality of Electric vehicles up.
Driverless electric cars in the 21st century are likely to improve the world in profound and unexpected ways, just as vehicles powered by internal combustion engines did in the 20th. But it will be a bumpy road. Buckle up. Follow our latest news to keep up with all the changes to the world of electric cars!
Did You know…Potentially thousands of car repair firms ‘face collapse’ after no-deal Brexit.
Did you know that within 2 weeks of Brexit happening at the end of this month, around 1,000 companies across the UK car-accident repair industry “could be on the brink” of closure. According to experts it could mean the cost of repairing your car would increase significantly due to parts becoming more difficult to come by.
Body shops that repair cars in accidents face a very uncertain future, business leaders warn
Body spraying a panel in a body shop – the Government has been accused of doing very little to help the industry which depends on speed at the border
New border checks risk slowing down business dramatically for an industry which relies on getting car parts in quickly from abroad, including Europe.
The Government is facing calls to take a ‘no-deal’ Brexit off the table from the car industry
According to car industry experts, the car repair industry had been ‘severely underinvested in for many, many years’ and therefore didn’t have the reserves to step up to the difficulties of a no deal – if the supply chain was hit with delays. Meanwhile Kate Goodwin, who fronts the repair programme and supply chain at The Innovation Group, an organisation which supports industry, added: ‘Repairers don’t get paid until a repair is completed, margins are tight.
According to the government the priority is to deliver a deal that will protect UK jobs and prosperity and provide certainty for businesses as we leave the EU. The Government is preparing to ensure the country is ready for every eventuality.
What we say is if you are in Widnes then don’t panic Brexit is potentially going to happen at the end of this month. The good news is that Widnes Auto Electrics are fully prepared for all outcomes and will be able to continue to provide car electrics for you regardless of the outcome
This 3 series came to us after the dealer said there was nothing wrong with it.
The alarm was going off intermittantly.
A quick code read showed several faults
Testing the car seemed to show no faults .
But looking at the BMW site it showed a TSB (technical service bulletin) for this fault. The switches in the door become worn with age and set the alarm off.
The solution is to reprogram the frm module and this gives the switches larger tolerances so alarm doesn’t go off.
A lot of learners are caught out during the test, because they aren’t aware of the difference! Whats worse is that fact that you are probably reading this document because you have passed your test either recently or some time ago and despite being on the roads every day you no longer know what the rules are!
Thinking distance is the distance that the car travels after the driver has seen the danger and before the brakes are applied.
Some peoples reactions are faster than others, but the average distance it takes before the driver realises the danger ahead is 20 feet, when travelling at 20 mph.
The distance that the car travels whilst braking. With the brakes applied the car slows down, and the average car will travel 20 feet before coming to a complete stop, when travelling at 20 mph.
The Overall Stopping Distance is a combination of the 2 above.
When trying to visualise a distance it is useful to remember that the length of an average car is approximately 15ft, therefore, 75ft would be about 5 car lengths away.
The Overall stopping distance when travelling at 20mph is 40 feet (12 metres).
This is made up of: (thinking distance: 20 ft (6 m)) + (braking distance: 20 ft (6 m))
The Overall stopping distance when travelling at 30mph is 75 feet (23 metres).
This is made up of: (thinking distance: 30 ft (9 m)) + (braking distance: 45 ft (14 m))
The Overall stopping distance when travelling at 40mph is 120 feet (36 metres).
This is made up of: (thinking distance: 40 ft (12 m)) + (braking distance: 80 ft (24 m))
The Overall stopping distance when travelling at 50mph is 175 feet (53 metres).
This is made up of: (thinking distance: 50 ft (15 m)) + (braking distance: 125 ft (38 m))
The Overall stopping distance when travelling at 60mph is 240 feet (73 metres).
This is made up of: (thinking distance: 60 ft (18 m)) + (braking distance: 180 ft (55 m))
The Overall stopping distance when travelling at 70mph is 315 feet (96 metres).
This is made up of: (thinking distance: 70 ft (21 m)) + (braking distance: 245 ft (75 m))

This Ford came to us with a cluster fault which the previous garage couldn’t solve because they didnt have correct tooling.
With the replacement cluster fitted car failed to start due to cluster being part of the PATS system (ant-itheft system).
But with the correct equipment the job is straight forward
With coding complete the car starts and runs.

A older Renault came to our workshop with a running issue.
Various tests were performed and the ECU condemned. Due to high cost of new replacement part a 2nd hand unit was sourced. But due to immobiliser coding 2nd hand part wouldn’t allow car to start.
But with our equipment we have at our disposal we are able to Virginise 2nd hand part then code it to vehicle.
AUDI A4 with display fault on the instruement cluster.
We removed the cluster and replaced the faulty display.
2009 mini was in our workshop with airbag light illuminated.
A quick code read revealed internal fault in module.
But here at Widnes Auto Electrical we offer a repair service. We can remove your original unit and with specialist equipment repair your unit saving you 100’s pounds
With the chip resoldered onto the pcb and refitted to the vehicle, the airbag faults are cleared and the light extinguishes.
