That is awesome, thank you!! Just one question: When you say radio, does that mean those are on the plugs for the radio, so when I install the aftermarket wiring harness, I can tap directly into the harness the aftermarket one plugs into? Also, any idea where I can tap into the reverse sensor or whatever for a manual transmission?

According to the print out I have the reverse wire is a red wire in the drivers kick in the group wires running down the drivers side (make sure you meter the wire. I know in my xb there like 4-5 other red wires in the bundle)
Most harnesses give you 2 illumination wires, one is ground the other in positive, most head units use the positive one (mine does but I also have an aftermarket nav screen) just meter the illumination wire off the harness to make sure.
