I'd suggest that you contact the seller of the new radio and ask for help. Most after-market radio sellers have adapters to fit nearly all cars. For example, look up Crutchfield and see what they offer. There may be one or two on this forum with wiring diagrams, but the wire assignments do change color from year to year, or at least body update.

 

Thanks Jack. As there was no adapter in the car I was hoping to just connect the wires rather than buy the male and female sides to the adapter. I didn’t realize they changed the colors so much, surely it would make sense to keep them the same!

 

Hi Bruce, welcome!

Not sure if this will help, but here's the radio connector wiring according to a 2008 manual. I apologize for the formatting.

Thanks Sandstone. From what I understand from this:

Red/LB would connect to battery wire from radio (yellow)

Black/yellow would connect to ground from radio (black)

Grey/red would connect to antenna from radio (blue)

White/org and white/pink would connect to acc from radio (red)

Does this sound right?

Thanks for your help

 

You're welcome!

To be honest, I haven't done a radio swap in one of these so I could be wrong, but I think the way it goes is the RD\LB "always on" I.O.D line (ignition off draw) is used to keep the memory up, so it goes is the yellow wire(?) and the canbus + (WT/OR) and canbus -(WT/PK) are what actually powers the unit, but how it's actually hooked up could depend on the radio you're installing. If you don't have an install guide or the guide you have doesn't give the details, I'd do like Jack says and get with the seller for some help. Better to be sure than blow something up.
