One on the large terminal with the incoming battery power cable on it and one on the small spade type connector which is responsible for pulling the solenoid in :wink: . it would be safer to attach one to the battery positive terminal to get your feed and one to the solenoid spade connector. I wouldn't want to be stuck under the van if you shorted something out or accidentally operated the started motor with the van in gear :mrgreen: , be careful :wink:
