89 sho, no jbl. Ok, having some trouble here. The wiring diagrams I have looked at on here do not match the wiring colors in my car. Previous owner sliced up the factory harness so I am at a loss here. I matched colors and checked my fuse #11 but can't get the radio to turn on. Here is a photo of the carnage

Speaker wire is not a problem. I need to get the radio to turn on. In my picture, there is a red, yellow, black, and orange wire.

Thanks for the replies, looks like I had everything hooked up properly. Now I need to get the harness plug out from behind the ashtray so I can inspect it. There appears to be a incomplete circuit somewhere. I did notice that I pulled the yellow completely out of the plug behind the ashtray and after i put it back in place I managed to get 12v to it. Any tips on getting this plug out where I can see it?
