Thanks for the quick reply!! I found the wiring diagram and will test the voltage and ground this week and report back.

Hopefully it is just the wrong bulb that would be the easiest fix. This is where it gets a bit tricky, so when I bought the car the person I got it from neglected to mention that the driver side brake light socket had been replaced! A completely new (and different socket) has been wired in with the old socket being removed. The wires were cut and rewired just before the harness clip part (Between the socket and where the wire from the socket clips into the harness). A bit hard to explain but I've included pictures of the driver and passenger sides for reference.

The bulb I am using could be the wrong one for the replaced socket is my thought. Not sure how to find the correct bulb for that socket besides trial and error. Have been thinking of maybe replacing the driver side brake light assembly with a new one. Will I able to put a replacement in and connect it to the harness? Thanks again!



Replaced socket, black tape is where it has been rewired (before the clip into the harness)
