Chronister Enterprises

I have tried for an hour to get the wire from the sill into the #1 port on the black X1 and it goes in but you cannot put the plastic retainer on it. I have flipped it over multiple time to try different angels. Not sure why this picture shows a different port than number 1. Any suggestions on how to get it pushed in far enough to get in the white retainer clip?

I need the answer to this also. I’m surprised someone with the factory installed sills couldn’t take a picture of the harness to know where it is plugged into.

Thank you very much. I will print this out and try it.

I purchase part number 85527846 from GM and no install instructions were included. I picked up the part from Billion GMC in Iowa City IA. I contacted them and they have no clue where the one single wire is plugged into which harness. Only paper that came in the box is attached. Anyone with the “accessory” install book who can look it it up would be greatly appreciated.
