I gave up for today! My back is sore from trying to crawl in under the
dash to find that @#$$# BCM and the grey plug. Surely Chrylser could
have made it a little easier to get at! I've finally managed to unplug
the grey plug and tomorrow I will see if I have continuity from the BCM
end of the Bk/Wt wire to the trunk end of the same wire. I'd like to
see if the BCM terminal is actually energizing but I think the only way
to actually see anything in there would be to dismantle half of the
car!
Thanks for all the help guys.
