Just got stock power mirrors; my 84 didn't come with.

I'm assuming the thick block connector in the middle of the picture is for the power mirrors, yes in?

There is a for prong coming out of each mirror; how is it all connected? I don't see a four connector receiver under the dash.

 

can't remember for sure as it's been quite a while, the wiring is already there in the cabin harness. just get the door wiring and u will see what's needed on that end. check the foxed.ca site for the wiring diagram.

 

You'll want to find the six pin remote control mirror switch and trace that out to each door. The four pin mirror connector mates with the door harness and then the door harness will tee off to the mirror switch harness in the cabin. You'll need to trace all that out under the dash.

 

Is this a door harness that would have a connector to the FB power mirrors? Is this what ties the actual mirror to the four pin split in the dash.

If yes should this be in the door, if wired for such?

 

Pages 66-68 in the 84 wiring diagram have it all.
