2004 Ford Explorer BCM Wakeup

For the fords your looking for a yellow/black or BLACK / YELLOW wire that will be coming in from the drivers door boot. There are two different ways to bypass this system depending on the vehicle. Normally you have to pulse a ground to this wire (split off your unlock wire with 2 diodes) hit the pink/light green with one and the BLACK / YELLOW with the other. The other way, (doc 1094) is for wires that rest at ground and need to see an open when unlocking. In that case you would split your unlock wire from the module and run one to the pink/light green wire (with a diode inline) and the other one to activate a relay which will open the BLACK / YELLOW wire. Also this is rare but I've seen cases where the vehicle doesn't have a factory alarm, but the wire you need to pulse is the standard GREEN/ violet OEM disarm wires ford uses. I've only had 1 case where the wire wasn't coming through the door boot and I had to pull the door panel off and find the wire. I've posted this before too sometimes you can get lucky and just program the vehicle to override this. Read the owners manual and look for a trim switch disable feature and see if it's tell how to turn it off.. Mike
