My son replaced a cam sensor in a Kia Optima 2.4 cyl and while doing it, the plug on the harness broke, being that heat and age made it very fragile. He got another plug, but cant tell which wire belonged where to be able…
My brake lights do not work. I have changed bulbs fuses brake pedal switch. it is not getting a constant hot to the pedal switch only with key on.
Sounds like you have gotten into a good one. Lets see if I can’t help narrow this issue down a bit. I like to start approaching electrical problems first by looking over the electrical schematic for the problematic system. We will work with the Exterior Wiring Diagram provided below. It appears as though you need to check two fuses, the STOP LP FUSE and the IG1 FUSE. Also check the HAC RELAY and the STOP LAMP RELAY located behind the center of the dash). Beyond that you are looking at checking the wiring and connections.
