Thanks Dave! I'm with you, only solder and heat shrink throughout. The couple of spots with thicker wires that required butt splices still got crimped then soldered.

I'll doublecheck all the wiring in that area. Just seemed to pop up after I put everything into the rear compartment to tidy up the car. Maybe the autoprom in there with close proximity to the wiring harness picking up something?

At least it isn't affecting the engine operation, correct?
