I happened to take apart the driver side kick panel on my 1992 C4. About where your waist is behind the panel was a wire connector with six wires. Black, Brown, brown with white stripe, green, yellow, and purple. It is a female connector. I can't find what it plugs into. It is near the orange wires going to the seat controls and has enough length to go up to the center console area.
Anyone have an idea what this is? Can I ignore it? Thanks.

 

Welcome to the forum. Hard to tell without a wiring diagram but could be for an option that didn't come on the car. That's a shot in the dark tho.

 

I appreciate your response. I think it is an option that wasn't put on the car originally. I will button it up an d hope for the best!

 

Sounds like a plan. I guess if everything works on the car then it's probably something that wasn't installed.
