I'd really appreciate some advice. My keyless entry system has a relay switched positive 12 volt pulsed output intended to flash the parking lights. That's the only tap into my 2012 Colorado wiring as I don't care about the horn and I'm using aftermarket lock actuators. I'm concerned about frying a relay or worse yet, the BCM. Is there a wire that I can safely tap into that will flash the park lights with a positive pulse?
