Also, something I noticed. The XScorpion wiring harness doesn't have illumination or dimmer wires in it. The 4100NEX screen is quite bright at night.
I looked at the Metra equivalent (70-7903) and it appears to have said wires. So, even tho it was a good price on the package, I probably wouldn't do it again. It would cost a little more to buy the separate pieces, but I think it would be worth it.
