92-93 mirrors wirings

I would like to know what do i need exactly to make the mirrors work.

Basically i have a 1991 non power and i just got a pair of 92-93 folding power mirrors with wire coming from it, Also i have the switch button so far. So what else is needed if like relay or other sort or does all 90-93 comes with prewired just incase the non power guys plans to go optional with power then its plug and play etc? or no…

Thanks guys.

I just got the USDM power mirrors built my own harness and fished it under the dash. It works and the only thing that you can see is the wires running to the doors because I didn’t have the time to snake the wires thru. I believ the folding ones have a relay so it should be hard to build. All you need is the schematic wires and soldering gun+solder. Then some ingenuity in terms of running it under the dash. Oh and then just a good ground point and a place to run the switched positive line.

so trying to get the wire harness is pointless? Is the schematic in the helms? I am very interested in doign this. I have the switch, just need to get the mirrors.
