Automatic Shifter | Center Console Lighting

Slight correction, I used something more like this. Exact same idea, though:

I don't have the carpet on my console right now so I was able to get a pic:

Never mind all that extra wiring in there, I have cruise control buttons and an OD button hiding in the ash tray. For the light, yellow is grounded and red is wired to power.
Totally awesome and helpful ... The build shop sent me a picture of the console underside this morning and we do have the metal housing, so just needed the wiring harness!!!

Just for sanity-sake, do you know where the wire/switch is located to trigger the reverse lights (in my case a light on top of the license plate frame)? I saw that B-body wiring harnesses have them in the center console, but the shop "thinks" it is located on the transmission.
