Bmonts, sounds like the main relay under the hood. I was going to do the same thing on mine when I did my coil swap. It should work, but you get a constant "Service Air Suspension" warning. The only way I know of to get rid of the warning is to pull the relay, which also cuts the power to the compressor. If you haven't been getting any warnings and have no power to the compressor, I'd say your relay has already been removed. It should be located sticking out from the wiring harness along the driver side frame rail, just inside the front wheel well. I actually ended up removing the whole stock compressor and replaced it with a Viair system, and have been very happy with it.
