Total Rear Light Failure

Thought I had a bad turn signal bulb on the driver's side rear but it is a larger issue. All lights on that back side are out. All bulbs are good. Checked fuses under hood and in the cab and all appear solid. Pulled the entire lens out and checked all leads. Don't have a diagram so I could not shoot the feeds but I intend to go back at that connector later this week. Beginning to think I compromised the ground in some manner when using pigtail to recently tow a Uhaul. Any ideas welcome.

 

Not sure if you've found any diagrams yet but maybe one of these will help? Also, just in case, these came from a FSM dump on T4R, it should be one of the first stickied posts on the 4th gen forum.

Good luck!

 

My buddy's incoming 2004 4Runner project also having rear light issues. The current owner said it started with signal lights acting up followed by the brake lights totally out. We'll just finish installing the bumper and bilstein shocks on the Silverado this week before we can clear the garage and take the 4Runner in. We'll definitely need those diagrams.

 

Many thanks for the schematics. I will give things another look this week. Appreciate your help!
