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.

Good Video Bro Need to do the big 7 upgrade on mine

[@alistairmaitland2123]

Can you explain why one would want to do change out all the ground cables? I'm wondering if this might be one of the causes of my rough start on my 2006 4Runner.

A strong ground is important in ensuring all your electrical components have the power they need to run your system correctly. Bad grounds can often appear as electrical gremlins and cause intermittent starting issues, rough idles, and more obviously issues with your charging/starting systems. I would definitely recommend checking your grounds first and foremost!

The first ground you show is that the one from the battery?

[@looseaxles]

All of them are from the battery - with the stock harness they just split a little further down.

I would install a Front and rear diff Breather I did on mine with a Arb Diff Breather kit came with enough to do both diffs and Transfercase and transmission the front diffs are notorious for not being able to breath because the Breather gets clogged its on tip right next to fuse pannel for the front

[@looseaxles]

Well worth it! That’s one of my first videos - I always try and relocate the rear breather within 3 days of getting a new Yota haha!

​@@looseaxlesthe front Breather for the front diff Is actually the worst to get clogged and its not even noticeable that they get clogged because there so high I have done a ton of diff repairs and replacments on customers 4.7l V8 4th gens because it Causes the pinion seal and bearing to Blow

[@looseaxles]

@AntonioClaudioMichael I’ll have to take a look at mine! Can’t say I’ve seen it in a long time haha.
