Satellite Installation

[93XLT]

I have a 93XLT. I'm installing a car dock for a Sirius satellite unit. I found a great place for it on the instrument cluster panel, upper right side. I took the cluster panel off and found a plastic panel insert that screws out and has a wiring clip attached to it with 8 wires. It looks like an unused option. Does anyone know what option would go there? I'm wondering if I can use any of the wires to power up the car dock.

Can you post a pic of the area and harness?
