Hello, I am trying to wire an after market radio which has several wires (front, back, left, right, etc) but the wires that were in my oem radio harness only number 8.

They are as follows:
Black
Red
White
White/Orange
Grey/Orange
Grey/Blue
Green/Blue
Green/Orange

Thanks for any insight. I have found the obvious ones, Red = ACC and Black is ground. Yet when I plug these into the corresponding wires on the new stereo, It does not power on. It has a wire for battery and acc, but I don't think there is a battery wire in the oem wires.

 

You're better off using an adapter to mate your radio to the Jeep harness.

Something like this - https://www.crutchfield.com/shopsear..._adapters.html

 

The adapters do not fit the new stereo. At some point I will need to wire and I'd rather just do it directly.

 

I have made some progress. By plugging both stereo power wires (ACC & Battery) into the one power wire from the oem harness, I am getting the new stereo to power up. But I cannot get the sound wired right. I'm not sure if the oem set up used a common ground for the speakers or what, but I am left with a black wire (ground) a white and white/orange wire (bus wires) and 4 speaker wires. But no combination of connections to the speaker wires produces sound.

 

with the Rubicon, you may have the upgraded sound system which uses a factory amp. i'm not sure if you need something to trigger the amp to turn on to get sound? in fact it may not even just be a +12v to the amp, it might be a CAN-BUS signal. like you may need something along these lines: http://amzn.to/2mbgffR

just a possibility anyway...

EDIT, after some quick research: if you do have the upgraded sound system, the factory amp supposedly uses a bus signal from the headunit to adjust volume, so you would need an interface similar to what i linked to work with that.

 

Thanks, this makes sense. I think I will run wires directly out to the speakers and bypass the oem system.

 

Any idea where the speaker wires come into this oem amp so I don't have to run new wire all the way out?

Did you ever figure out what you needed to do did bypassing the amp work or was it more of a pain??
