How to Upgrade the Battery Ground Wires on a 4th Gen Toyota 4Runner!
In this video, we go through upgrading the factory battery ground wires on the 4th gen Toyota 4runner using 1/0 gauge wire from Jeepcables.com - their products are seriously phenomenal and it works out to be cheaper than making a kit yourself. I will be uploading a big 7 install pretty soon here as well. In specific, we replace the following connections: 1. Battery Negative to Fender. 2. Battery Negative to Engine Ground. 3. Chassis Ground to Engine Ground. Overall, the install wasn't too hard, but the grounds can be a little difficult tor each. Id highly recommend removing your skid plate and fender liners to do this job.
