[QUOTE="ZOMBEAST, post: 15990309, member: 75857"] Answer is no. Key on power only goes to the fan relays. The fan relay coils are only energized when the pump is on, closing the normally open contacts of the fan relays, which then power the fans. Depending on your tune, the pump may not be on at all times. You may also want the ability to run the system with the car not started or while your driving. You'll need a switch that starts the pump to do that. I chose to wire a switch into the actual pump relay wiring. Had to find the pump relay which is in the small panel box on the p/s shock tower. Using the diagram on the relay, I found the two wires underneath for the normally open contacts. Spliced my override switch wiring there and routed into the cabin. This switch has no effect or interference with normal, tune, or temp operation of the pump. Use the pictorial diagram you posted for the wiring. [/QUOTE]
