I just completed adding OEM aux switches to my BB!
First to head off potential questions:
1. Why didn't you just get them from the factory? - Because I am a moron and didn't do the proper research
2. Why not just replace everything per this thread https://www.bronco6g.com/forum/thre...talled-diy-writeup-instructions-photos.35388/ - See #1 lol, Seriously though I was really not keen on replacing the fuse box and having to deal with the DTC code that might be thrown in the background or that I would screw something up and brick my Bronco. This way the aux switches are totally "out of band" on OEM harnesses, etc.
I already had a Auxbeam box and buttons but I really wanted the Aux switches because they are so satisfying to toggle. I knew they were just switches to activate a relay.
I ended up having to use a generic fuse/relay box on Amazon ($30) because something about either the relays or wiring in the auxbeam didn't work as I expected. Maybe it relied on momentary relays idk. But I did reuse the auxbeam cable they ran through the fire wall and cut the ends off the switch panel and box. The auxbeam had the right amount of cables, 6 for switches and a +/-. After a few hours with a multi-meter I was able to get the pin out of the board on the OEM Aux switch and using a raspberry pi as a power source to test switch illumination. And proceeded to make a harness. I purchased the correct ford OEM harness ($82) for the sole purpose of cutting the aux connector portion off as I couldn't find just the correct end anywhere. I also acquired the overhead console with switches for only $200 on ebay.
To swap out the console I just had to take two screws from the sun visor holder and then the center console pulls down far enough to access the four screws that hold the console in. then run the Auxbeam cable and tucking it in on the pillars and along the top.
Thank you for coming to my Ted Talk!
