Adding auto climate to XLT.
Would.be so.much easier if would interface with hsm same across both bezel options. Guessing 2 different mechanisms for heating seats.
Sorry for the late update guys. I'm overloaded with work right now trying to get issues taken care of before the holidays.
Update: I put most of the board together last Friday to test. I found out I used the 5x5 QFPN package size instead of the 4x4 for the CAN controller and I oversized the micro by one size also. I already fixed the first in the design and I'm planning to fix the second tonight. I can test the on-off functionality with what I have right now, but I'd have to get another set of boards done to test the full micro functionality and the CAN comms. I could order the mass quantity now, but I'd prefer not to take the chance the schematics are right and the two wrong-sized packages are wrong. I can't think of the last time I've been successful doing things that way personally or professionally. I'll see what my options are and let everybody know when I pick my next step.

Agreed please don't take our being anxious for being impatient, at least for myself I am just happy that there is a possibility that this can work, I think I said it before but... Just don't forget me when you finally get everything together 😁
Can someone please share the part number for the bezel i would need to buy to complete this mod in a 2019 XLT with NO heated seats? Sounds like it should be plug and play for me since i dont have to deal with heated seats, and possibly a few FORSCAN tweaks?
