Get me the model spec and I'll see if I can dig an install manual out for it.

What year is the Mondeo again? I am wondering if the installer has somehow wired into the original alarm wiring (as that shuts the mirrors on arming, etc...) or has tapped into a "can" wire if yours runs it (depending on year).

As for the doors not locking on the aftermarket alarm, the installer has probably gone straight to the door looms with the alarm wires instead of through a relay and has "nuked" the supplies (they are only 500mA negative max to run a relay, not directly sourced).

Same as I bet the installer has gone to a door pin switch wire near the GEM module for the door sensing, not the A-pillar where he should have gone.

You should have my number, if not Mick has it, so we can always sort something out.
