okay further inspection. These two wires have nothing to do with the brake lights. though I still have the issue. there is one ground wire. one wire goes to the switch then the wire block behind the head light, and one wire goes straight to the wiring block behind the head light. all seem to have good conection. and the ground is good.
So I bought a pretty clean xr4 a month ago for a very good price. Though it has a few little bugs. namely the brake light. when I hit the brake the brake, the light dims.... I've unwrapped the wiring harness all of the grounds seem to be in order though I found a few wires that were just snipped by the previous owner. I have no idea what they go to. I know I havent left you with much. but any ideas?
