Anybody done the 1st option listed above? I think I found the wire green with an orange stripe? Seems to have a plactic or some sort of non metal covering. Would need to be removed I suppose in order to ground. For north texas it was cold this morning 20ish degrees. High idle would come in handy. Also noticed this morning while moving the truck the voltage meter was fluctuating between the normal range and almost down to 8, anyone else seem this?
Thanks, Patrick
