Is your seat belt mouse working for that seat? If not, I think that is the plug that tells it when to move. Kai
mouse? what? the power seat works yes i thought maybe someone worked on the in the panel behind the seat and forgot to tuck it back in..???
There are a few things in there that are not connected. I think that one was the ABS tester or something like that. I'm sure someone will chime in that really knows. Just take that panel off and put it back in there. The alarm ECU is behind that panel along with other crap.
Often service guys will leave that plug out so they can plug in their diagnosis equipment easily, I always tuck mine away after they had a play with it. (We are still talking about the plug, right? )
