When to pick up a tow dolly to drag a 1982 SR5 home and found out only my running lights work. After a lot of reading , I checked the fuses , I can feel the relays clicking when unplugged and plugged back in. If it's a relay , the truck will be getting a WAY more reliable Walmart wiring harness for 24.99 , I refuse to replace relays as im already unhappy with this factory harness , all my other trucks had Walmart harness with no issues.

Anyhow , I took a picture of what could be the plug for the wiring harness, anyone know for sure ?

 

I went with the factory trailer wiring stuff because at the time I could not find a universal kit. I figured nobody made one because the wires at the lights were so small like 22 gauge . Maybe somebody makes one now, it was ten years ago . It was pricy but them universal kits never lasted longer than two years for me so in the long run they cost me more.
