Homelink
 

I have a 2015 challenger sxt trying to find harness for the homelink from the unit itself

Where are your homelink buttons? Visor? Overhead console? That would be the place tom start looking.

In that car the Homelink will be in the overhead console as a standalone module. What are you trying to do?

I was able to get the oem overhead console with the homelink in it just need the harness from the overhead home link to the door post to install power and back light
