well.. i ran into a problem lol.. when the ignition is on the 12v reference wire from the BCM drops to 5 volts for some reason which is not enough to trigger the relay... soooooooo i tapped into a constant 12v source (radio harness) and it works.. but now the automatic headlights don't come on, just the parking lamps.. no big deal really, i can turn them on manually.. but the DRLs have successfully been killed!
