How Much Does It Cost To Rewire A Car?

Probably the most frequently neglected maintenance item is a car’s electrical wiring system. Most auto owners are concerned about the engine, tires, fuel, and other components. In comparison to the wires, even cleaning and washing take precedence. In actuality, however, the wiring network is what makes all electrical components work. Determining the best way to safely rewire a car is, therefore, crucial.

Time, perseverance, and skill are required when rewiring a car. Since a novice won’t be able to handle the complexity, it is preferable to have some prior experience. It would be better to plan the whole process ahead of time and make a rough sketch of the electrical wiring system.

Below CarMats will show you the cost and how to rewire your car

How Much Does It Cost to Rewire a Car?

Rewiring a car can cost anywhere between $1,200 and $1,500, depending on the type of car. $1,350 is about the average price. To see the price variations, request quotes from several businesses. Ask them to explain the process if one wants to charge more.

Due to the wide range in labor costs—from 50% to 80%—the cost of rewiring a car can be very variable. The price of your service could also be impacted by other parts, such as the engine or electrical system if those systems need to be fixed as well. It is therefore challenging to estimate the cost to rewire a car with accuracy, but you should plan to spend at least $1,000 for a good job.

How to Rewire a Car Safely

To complete the task swiftly and safely, you should strictly adhere to the instructions when thinking about how to rewire a truck or car. When rewiring your car, adhere to these precautions to keep you and those nearby safes:

Turn off the car’s power

Power must be turned off and all devices must be disconnected before beginning. The battery cables should then be disconnected by first removing them from their respective terminals and then loosening the bolts on their nipples. Once they’ve been taken out, secure their placement so they won’t touch exposed metal components or one another.

Any extra wires that are attached to the battery terminals can now be removed. Put them aside and wrap them in insulation tape.

Cut the main wiring harness

In the engine compartment, look for the main wiring harness (it should be routed through its own rubber grommet). Pull every old wire out of its grommets on either side after cutting it between the engine bay and where it enters your cabin. Don’t cut any other wires unintentionally, please.

Strip off the wires

A numbered label should be affixed to each wire end after a centimeter or so of each wire end has been removed. If there are many different colors involved, you might find it helpful to have a multi-way crimping tool on hand for this part.

Reattach the wires

In order to proceed, you’ll need to refer to your owner’s manual because things start to get a little more technical. The basic idea is to reconnect the wires to their original locations after reattaching them in the proper order so that everything makes sense.

Press each wire firmly into its grommet after reconnecting everything, then put everything back the way it was (battery cables, etc.). This will take some time because there is a lot of crimping to do but don’t rush it, or mistakes could happen.

Test the wiring

Make sure there are no illuminated warning lights on your dashboard before turning on your headlights. Start the engine, and if any remain after a few seconds, immediately turn it off and go over everything once more to ensure that the issue is fixed.

Check the electrical system’s functionality and, if everything is in order, turn on your headlights once more. Any issues here will probably be caused by bad connections or wiring. In order to check for errors, you must go back and review everything.

Finish the task

The final step in rewiring a car is this one. the engine bay area by replacing any damaged trim panels (side skirts, for example). Restore everything to its original position afterward, then seal the gap.

OEM wire harnesses can be purchased and used for a significant discount compared to purchasing them brand new. This is frequently a much more economical option, provided it is still in good condition. However, it’s critical to replace your existing wiring as soon as possible if it has suffered corrosion or burn damage. If handled correctly, your car will be safer, and you won’t have to be concerned about urgent repairs for a very long time.

Conclusion

This is a safe method for rewiring a car. Follow directions carefully according to your owner’s manual if you’ve never worked on a car before. Parts will avoid damage by doing this. After starting the engine, if you continue to see warning lights, you may have acted incorrectly. Take the vehicle to a repair facility in that situation so that the issue can be fixed.
