Hello everyone,

I am trying to figure out which wires in the head unit are the rear speakers. I am running a LOC for the amp. It’s a Lt with Bose system. There are three plugs, green, brown and black. Im assuming the green is the speakers….. best guess. I see a lot of post blue/black etc….. but I have no such color.

You would do well to find the wiring diagrams. Some members here use All Data DIY as a source. I've never used them myself.

With that, you'll learn that you'll have to distinguish between the various InfoTainment options available that year so you get the correct diagrams.

Does anyone have the wiring diagram?

Wiring diagrams are part of the service manual which is purchased and used under license. The official distributor, helminc, charges $299 for an electronic version and $475 for a paper set. The AlldataDIY option @DrivenDaily referenced is a much cheaper option and is officially licensed. The current prices are $19.99 for a month and $59.99 for a year. Again, it is a license and distributing the material publicly is a felony. Alldatadiy is the option I use and can confirm it has all the wiring diagrams you need.
