Need stereo install help please..
 

Ok so im putting in a pioneer avh210ex and I wanna know what harness I need so the entire thing is plug and play, dont wanna cut/splice any wires if I dont have to but realize this may not be an option.. I have a couple (axxiss is it called) harnesses. One for '98-08 gm and one for 00-05 monte. I believe one of these I can wire to the pioneer harness but dont know which exactly. Anyone know a part number to the correct one?

What other info could I give so you can help me out? Its been a long time since ive done this type of thing and when I did I wired the entire thing myself but for this I need XM/Sirius to work along with you know, all the other computer stuff for the car.

Thanks in advance..

So different stereo going in.. Pioneer AVH-4200NEX

Which wire harness is needed, anyone know? Wanna keep my XM. THIS stereo IS xm ready..

Does someone know where I could get the info I need? Like, where could I look up what wire harness I need to go from my stock harness to the pioneer harness.. I have now realized I need to wire these two together but dont know which one I need.

Ok so I figured everything out I needed to except one thing... My dimmer works opposite of how I want. Turning the dashlights brighter, makes the stereo dim. Dimming the dash lights makes the stereo brighter.. Anyone know whats up with that??

Possible that the wire is backwards / upside down? Maybe your resistor is running the wrong way?
