What have you done to your 5th Gen 4Runner today?

Here is your solution, I did this 4 years ago with no issues since.

Hope this helps.

 

discovered this issue was just a bad ground and fixed it

 

TEQ off-road under hood lights installed. Easy and well worth it. Also installed a nice little bus setup.

 

My 2017 tundra battery died after 2 years. No mods or extra electrical adds. Didn’t have time to go elsewhere for a battery so dropped it at the dealership. Service guy called and said he could put the same type battery in for $200, or a lifetime warranty one for $250. No pro-rated bs. Pretty obvious which way I went. Of course this was 5 years ago so I have no idea what they would offer today.

 

That is a nice bus setup and what an efficient use of space over the fuse box. Great idea on the hood lights.

Have you considered a fuse bar like this? so wires off the bus are immediately fused.

I have an older version of this one (mine doesn’t have the LCD screen)

Works great. It has a boost button which starts the 4R right away
