Sure.

He'll repeat what I said.

he didn't say much about it, he took a look at the other diagram and noticed the ground wire on 87A was missing in the diagram. I showed him the other diagram and he just said it would work but over complicated for no reason

the only thing missing in the diagram is a ground wire to the 87A terminal.....:)

now i just have to figure out why the module to put the windows up when I hit the remote locks moves the windows up a 1/4" then stop....
Dang, you jogged my memory Steve! I had exactly the same issue. Sorry I didn't remember. I'm losing my mind.

don't worry about it, it happens all the time to me. Figure out how to fix something and by the time I have to do it again I forget how to do it...

It was like three years ago when I did that. I don't think being under general anesthesia twice last year helped my memory, but hey, my colon and bladder are repaired and I survived, so I'm grateful.

your health is alot more important than trying remember simple stuff. The mind has a way to clear out some stuff to make room to deal with the important things...

I wonder what the grey wire is for...:D

Ve have Vays of knowink vich vire goes vere!!!

You can see that in this picture:

The Center wire of each relay (87a) is a large gage black wire that goes to battery ground.
The 85's go to ground, also.
87's are large gage Red wires to battery +,
86's get the wires from the switch Blue/wht for up, Blue/blk for down, these are + when switch engaged
30's get large gage wire that goes to the window motor (Relay with blue/wht 30 goes to Blue/wht window motor wire(up), Relay with Blue/blk 30 goes to blue/blk window motor wire.

If you run a fused 10 gage Red/Black wire to each door, the relay wiring is actually pretty simple to do on the door and only a few more connections than the LMC harness... but the LMC harness makes it pretty simple to do.

I would have bought the LMC harness but being in Canada it would have been around $60 to $70 to my door with the exchange and shipping. The relays, wire and connectors cost me less than $20 and with the help of you guys it's working. I use 14 gauge wire with a 20 amp fuse. The 14 gauge handles up to 32 amps so that is more than enough for the windows and it's the same gauge of the original window wiring. .....now I just have to figure out to get the module to put the windows up....

The diagram that Jared posted works on both doors of my GP with a ground added to 87A on each relay
