i have a sony xplode head unit in my redline, for me it was a pain trying to get the correct harness. I ended up taking the factory radio inside the retailer. come to find out the adapter to an 04 malibu is what it takes. hope this helps .
i bought a wiring harness a while ago but never got around to puttting my cd player in come to find out the harness changed for the 2004 ion so i ended up buying the wrong one. the part number for the 2004 ion is 70-2103. can't remember if it was metra or sochse and i'm too lazy to go look
The steel braided line is an earth unless I'm much much mistaken.
Do you have the Advanced audio? I just had the stock. I reckon if you've the Advanced kit you might have different wiring to me. Bascially I took the harness from my old saturn which was all labelled and rewired it with the new one matching up the appropriate wires.
It sounds like yours is the same as mine, the 04B was way, way off ... wires in places that there were no wires on the factory plug etc...As soon as I offered up the GM10B it just looked exactly right. It was easy from there on in. Buy.com was the cheapest and it came 2 days later.
Sucks though that there's zero information about this anywhere. I suppose Crutchfield would've been helpful but even their site doesn't have the correct plug listed.
Sorry I couldn't help more but I'm at work and cannot get to the car until tomorrow....if you do want pictures then let me know as I can arrange that.
Yeah I went to circuit city a few months ago bought everything and then got home and went to work. I soldered all the wires pro like heat shrink wrap on all the wires ya know. Spent all that time then no way does it fit in the Damn car. I called today for the part to see if they had the right one now. The guys like yeah we have the one its for Saturns 02 and up. I was like noooo he said its the one. Then I called him worthless to the audio community and hung up. Then I came on here after searching and found the GM10B model and you posted the same number. I just ordered because you said the exact #. Thanks a million.
