SoCal is a BIG place! What part of of the area do you live? There are many good shops depending on locality. "Mr. B"(?) in Encino is highly recommended. Look in the "Recommended" shop portion of this forum. Pick a couple in your area and ask the forum members what their opinion is. You have a main wiring harness and a smaller one that goes down to the starter. replace that one also. And yes, if you don't have EPC sign up for it. It is free to end users. Good info that is for your specific VIN numbered car.
