[DML] Re: Door Harness

[Peter Lucas <lucas@xxxx>]

The wire looms from the doors terminate in connectors in the middle 
of the roof. To access them, you must remove the T-roof piece of 
stainless (easy enough), peel off the big piece of duct tape you will 
find under it, and remove the glued-on metal plate that serves as a 
cover to the wiring cavity. I am unsure whether the two sides of the 
lock wires join there or further upstream, but by accessing this 
location you will be able to determine unambiguously whether the 
short is in one of the doors (and if so, which one), or inside the 
vehicle. If the former, you could do the swap with the unused 
green/white wire (although you then couldn't use it for Daryl T's 
wonderful automatic door opener setup). By the way, the green/white 
wires go no further than the roof connector. Their mating positions 
in the connectors are empty.

If the fault is upstream from the roof connector, it isn't too hard 
to run new wires from there to the inside of the vehicle. You have 
to remove the rear headliner, under which you will find a big rubber 
grommet/bung thingie through which the loom enters the vehicle from 
the roof. Partially remove this grommet and squeeze the new wires 
through it. You can route them down the side without removing the 
speaker grill. While you're in there, you may as well run some extra 
wires so you can use those red/white wires into the doors in the 
future.

One note: in removing the T-roof on later production vehicles, there 
are two screws not mentioned in the service manual near the center of 
the door torsion bars that need to be loosened. These are apparently 
absent in early vehicles.
