First Gen Trailer Wiring Issue

when it's goes to the trailer the green feeds the right blinker and right brake. I think it's the Resee box that causing the trouble. since both on the right side does not work when it acts up but the left is fine it is probably this box.

 

ahh, the trailer side, my bad, thought you were talking truck side

I'm on my 4th or 5th box since I've owned the truck. they tend to wear out even when not used. brand doesn't matter either :/

 

this one was oem 2004. I just installed a universal one for LEDs. maybe it will hold up. it appears to be working fine now but I have not hook the trailer to it yet.

 

Does anyone have a tow wiring diagram?

 

What specifically are you looking for?

wires are standard unless you need the wire colors from the Toyota referencing what function they perform?

 

Just trying to get the running/parking lights to work… trying to figure out which wires do what
