PW Lock and Window Upgrade

[EdRo]

Hi All,

I'm doing the same swap that is detailed in this post:
https://www.broncocorral.com/tech_library/the-bronco-ii-project-door-swap-upgrade/

This statement is where I'm stuck:
"With the power door locks, all you really need to do is add power to the BLK/WHT wire, and ground the white wire."

The doors I got from the salvage yard do not have the blk/wht wire, or the white wire for ground. I only see a solid black wire on the lock portion of the switches, and in the harness. I've got new lock motors, tested and installed. But nothing is working through the switches.

Any guidance from the experts here?

Thanks,

Eddie
