How to make your own ground wires.

Ivoidwarranty

This is something I wrote up for a different forum a while ago, but it works for everyone. I'm not a big fan of the connectors I used in this write up but there are hundreds of different connectors out there for you to choose from.

There are many reasons to upgrade your car’s grounding system. Adding more electrical loads, such as amplifiers for a sound system or electric fuel pumps, create more draw. Often, stock ground systems are already maxed out and could use a little help.
I’m not here to sell you on the idea or debate if you should add to the stock grounding system or replace the stock wire completely. A quick Google search will give you more reading than you will ever care for on that subject (search for ‘big three wires’). Also, finding the points where you want to attach the ground wires to is completely up to you. You don’t have to use the stock location every time. What I want to show you is how to make these wires blend into the engine bay.

For this project I used a 4 gauge wire that I used before on a past project. Read that as “free”. TechFlex Clean Cut (1/4” for 4 the gauge), heat shrink (1/2”), and various ring terminals.





Measure the amount of wire you need and cut the wire to length. Installing the ring terminal is up to you. Crimp it or solder it. And then slide the TechFlex on.




Use the heat shrink to secure the TechFlex and cover the ring terminal joint.


Slide the rubber protector over the end.




Look at these slick wires.




Then go install it.

Here is a little more info:
