Expert Reply:
Your 2021 Buick Enclave has a wiring pigtail and not a connector for wiring a Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR. The 4 wires are located below the OBD2 port behind the side kick plate(see Image). This is where you will be able to attach the included pigtail using the Heat Shrink Butt Connectors # DW05744-5 and # DW05745-5. You will only need 2 of each connectors for the 4 wires that connect to the brake controller pigtail.

The 2021 Enclave, without OEM trailer package, did not provide the brake apply signal on the white/blue wire. I'm trying to get the dealer to see if this can be reprogrammed.

I can’t find the trailer wiring shown in your picture in my 2021 Buick Enclave. You have a still picture of it and we need to know if you had to unwrap that wire harness from other wire harnesses. It is so hard to find.
