My name is Ed. I have checked the electrical schematics for a 03 Chev p/u and an 06 Cadillac and cannot find any relays used in the power mirrors. I think the reason that the seller of the switch I purchased on EBay states I would need relay(*) was due to the 150 ma rating of the switch. Originally, I was thinking of putting one relay in the switch circuit much the same as a horn (or air horn) circuit, but was not sure if that would be the appropriate thing to do. I looked on EBay for Cadillac power mirror switches but none came with pigtails etc and to try to figure out thje wiring would be next to impossible. Hope this info helps. Thanks
