How do you disconnect the wiring harness on a 98 Pontiac Sunfire?
You seriously do not want to start doing that unless you can follow the wiring diagrams in the back of your Haynes manual. Even then, it's a tough job, because even if you are successful you are going to end up with miles of greasy, filthy cables, the color of some you can only guess at, some of which are wrapped tightly in electrical tape. Don't even think about it unless you are doing a total body-off restoration of something.
Where can you find a wiring diagram to show you how to hook up a trailer wiring harness on a 1998 Pontiac Transport?
99 sunfire your daytime running lites dont work and when you put your regular lites on the right one stays dim?
I have (had) the same problem with my 2001 Pontiac sunfire. After doing research online, one explanation is that the wires in the wiring harness are so small that they easily corrode. On mine I tested the wires from the fuses to the lights and moved around the wires and after that they would work for a bit.
