Anyone know what this plug goes to and what its for? Trying to clean up the hack job the previous owner did on this car/make sure everything is connected that's supposed to be.... And the list of hacked stuff is long.

I'm new here, I should have a full post up on the car in a week or two once it's running again(hopefully)...been a two month project so far.

 

Diagnostic plug, locates to a bracket behind the glovebox.

 

Thanks for the quick response, saved me some serious searching time!

 

What do you plug into it? Do I have to be a dealer to know? I think I have similar, excet there are 2 jumpers stuck in it. Did someone forget to take them out or is there some secret mod? First thing tomorrow I will get a photo. Weird.

 

Here it is - what is it?

 

Any idea?

 

xsbank-

That looks like the Alarm module connector which has been jumpered, bypassing the alarm.

 

That makes sense as the original alarm is gone, it had an aftermarket alarm that didn't work so it's gone too, now I am chasing wiring gremlins. My sunroof quit working and the rear hatch release never worked and they are on the same fuse. I also have a pre-1985 sunroof mechanism with a post-1986 ignition switch and interior so the wiring diagrams are betwixt and between!
