Great info here @flip @jh3113
Last piece of the puzzle is connector 410/411, which I believe to be a Molex MX150 20 pin.
Given this information, we should be able to run wiring from the BCM through factory connections and FORSCAN code the indicator signal.
Thanks, Iāve found the wiring schematics, but am searching for what part number pins to order. Looks like the Molex part number (33482-3602) is listed in your post for the taillight plugs (attached), do you have that info for the BCM connector? This should help determine which pins to order from...
Any idea what pins are in the BCM and taillight connectors? Or how to determine which ones to use? Mouser electronics will sell most pins in small quantities. Probably $20 or $30 in pins and wire to get it done.
This would also be good for people looking to upgrade to factory LEDs.
