Have a switch from center console of a 6 series,(salvage yard item). I bought it because it's the same size as my emergency flasher, and rear defrost switch on the dash of my 3 series. Cool switch, suspect part of an alarm system. Has a long button at top, 3 reset holes across center, and 3 smaller buttons across bottom with a green and a yellow light between those. 7 wires from plug. Have continuity across 2 of these, but haven't found any switching yet, 2 I read may be coil of a relay, but didn't want to drop power across them till I knew more about it. Any help ?
