Installing a 2006 Chevy trailblazer ss chassis under a 55 Chevy and would like to use bcm but have disconnected power door locks because I didn’t need, didn’t think about passcode 2 alarm, truck now in alarm. Is there anyway to still use bcm for other functions without door locks?
Thanks Jeff

I've don't know for certain but I believe as long as you use the ignition the absence of the door locks should not matter. Have you powered the system up?
