Hello, I have a 99' RR and my climate control is bad. I was wondering if anyone had a pinout of what wires are power and ground in the back of the unit? It has 4 plugs. I was going to try apply power to the reds and grounding the blacks but I dont want to fry anything Any wiring diagrams out there?

Thanks!
