RetroDelta88

Ok here's the deal...

With running lights on everything lights up the way it should. Pass side turn signal works fine. Blinks like it should and all lights work. Flip on the drivers signal and the corner marker turns off and front and rear signal lights go constant. The rear socket was replaced and installed badly. I removed it and re installed. Checked lights again, same problem... All the wiring and such in the front of the car is completely fine....

Also throwing a code 12 which is a problem with the ignition module but the car starts and runs just fine with a little hesitation.

Help !!
