2010-2024 Toyota 4Runner Gen 3 Dual Battery System

I love the final product! Took a lot of patience and it was more difficult than expected. The nutserts felt impossible with open ended wrench and socket so I dropped an additional $50 to get the proper tool. Now I’m ready to add accessories!

Really helpful and easy to install

Easy installation looks great. I only have 2 sets of lights and my new dash cam hooked up to the battery. I will post a second review in 6 months after my winch, and 8 additional pairs of lights are installed and used for a few months. But so far, I am completely satisfied with this amazing setup.
