Hi folks.
Over the weekend, while my car was disassembled, I installed a Fiesta Titanium Auto-Dimming Mirror. I followed the procedure roughly outlined in this thread here: https://www.fiestastforum.com/threads/fiesta-titanium-auto-dimming-mirror.6840/
I tapped into the wires in the map light console for power and ground, as indicated, and then ran a wire down the a-pillar and tapped into the +12v reverse wire in the kick panel.
However, this has caused an admittedly hilarious issue. When the mirror is plugged in, the rear map lights will not turn off. Not the dome light, just the two individual aimable map lights. Additionally, when the front map light switch is set to "door," the front map lights only dim about halfway instead of turning off. Flipping the switch to "off" turns them off all the way. Unplugging the wiring harness from the back of the mirror immediately resolves the issue.
Unfortunately, D1JL has passed and Canadianguy hasn't been on the forums since 2019, so I can't ask either of them for their help.
Can anyone think of what went wrong here? I am trying to avoid adding more add-a-fuses and other such things into my fuse box - and god, I do not want to have to pull the headliner and A-pillar trim again - but I am curious generally as to what's going on and how to fix it.
Cheers!
