Hi folks,
Been trying to get trailing wiring set up on my 2018 Model S 100D, using the Tekonsha ZCI 119251. These are what I've found for wiring on my car tail lights so far (couldn't find any matching posts with this details, hopefully it may also be useful for someone else):
Driver Side:
White/red - Left signal & brake
Blue/red - Left signal & brake
Gray/red - Left signal, brake and tail light
White - High when lights off, intermittent on left signal, high when tail on, off when brake on
Black - Ground
Passenger Side:
Yellow: Right signal & brake
Black/red - High when lights off, intermittent on left signal, high when tail on, off when brake on
Brown/white - Right signal, brake and tail light
Purple/black - Right signal & brake
Black - Ground
I've tried multiple configs from the Tekonsha instructions - trying to get the "A - 2 wire system" working using white/red on left and yellow on right, plus brown/right on right for tail, and brake not used. Also tried BTT, with left signal on gray/red and right signal on brown/white, with tail & brake disconnected. So far, not a lot of luck. It seems I can get tail lights and brake lights working, but no luck getting anything from the signals in either config.
Curious if folks have any ideas or see any issues. Thanks!
