OK. I'll work on these ideas and contact John about a new heater toggle switch.

I'll double check the leads in the harness connector the lights run through and at the light switch.

The harness for the parking lights looks definately incorrect. There's nothing on the harness to ground to the light housing. I remember wondering about that when I installed the harness a couple months ago - fiberglass cars need a ground for virtually everything. I guess I could splice into the black wire that loops through the wheel well from parking light leads to headlight leads and connect it to the housing for ground - but if the separate ground from left to right won't impact turn signals I'll leave it as is.
