Hi, Im in need of a radio wiring shematic for a 2006 GMC Sierra 1500 SLE 4X4. I looked at many diagrams and none have matched up fully with the wiring in my truck. It has a thick orange wire, red wire, thin orange wire and a black/white ground wire. Then the speaker wires are all the same as the other diagrams I looked at: (yellow and brown, light blue and dark blue, light green and dark green, tan and gray), but none have the thin orange wire. Wired it up and it turns on but doesn’t produce any audio. I blew the radio fuse first attempt any speaker fuses I dont know about? Thanks for any and all help.
