I picked up the extra OEM climate control ( thanks @ranma21 ), and started the process.
The good news: I think I was able to figure out transplanting the HVAC amplifier board and tying the provided harnesses together.
The bad news: I appear to have been provided the wrong stereo cable(s) (maybe for the LX ) because none of the "Tesla" stereo connectors match the TLC stereo connector![]()
Same thing happened to me. I bought from Rhino Radios and the included harnesses dont fit anything at all.
