Seriously gross. Ford should be embarrassed. How about desolder the relays on the module and replace. Any electronics repair shop can do such a thing. The relays are available through Allied.
I'm speaking to the proposed repair...not your workmanship.
Now we have dead relays in a module doing nothing, a couple pounds of box and wiring and relays that are redundant and unnecessary and clogging up an already crowded area, and a bunch of crimp connectors. Ick.
I prefer this method. https://www.youtube.com/watch?v=fYvZg0q7Seo
It can be done much faster if you spring for a decent soldering station and one of these. https://www.digikey.com/product-deta...EaArQREALw_wcB
