Default 3 Wire to 2 Wire Headlight Conversion

Hey all, doing a 2 wire conversion on my 85, got it all put together and only my driver side opens, doesn’t close, just opens under power, what could I possibly have wired wrong, as well as what could be wrong on the car, I found the fusible links that associate with the headlight motors but they seem to be alright, not burnt or nothing, any and all advice is appreciated, I tested the motors and sent power to both and those are good, just picked them up brand new off rock auto.

Unless things have changed, it's not that easy as the old system uses limit switches and relays while the newer one uses a current sensing electronic module. Mid America sells (sold?) a conversion kit: https://image.mamotorworksmedia.com/...les/601687.pdf

I think I've got it wired up right now, been digging through my shop manual, to check all my connections and fusible links, all of that is well and im wired up right, but now I need a control module it seems, I blew something out in the testing process, tried soldering a wire in place and it worked but not for long. Any other input on this would be appreciated though. I can manually power the motors with the harness in the car and they work great, so much smoother and quieter than the old style 3 wires.
