oh damn....that is the same kit I have....I will have to post a photo of the controller. They have a couple of different ones....just not sure I am going there right now...seems to be running pretty well without it... I drove up there 3 hrs, and every hour after that I was making a run...no cool down, other than having the hood open. Jake was running his trunk cooler....lol.... I think I am running pretty good right now.... thanks for the heads up Les...
