WannaB Posted April 1 Share Posted April 1 Good morning Does anyone have wiring chart for radio in an 07 Mack Granite CT713. I bought a new radio for my truck and upon going to install found all the wires going into the radio are all the same color.

0 Adkat Posted April 2 Share Posted April 2 G'day David, can figure it out without diagram. There will be 3 main wires, constant battery+, switched ACC or IGN + and a ground, just need a test light/ circuit tester to find them, the rest should be speaker +/- which you can check using a 9v to find the pairs, speaker will crackle when you got the right wires. If you've got steering wheel controls, should be on a separate plug to the power and speakers. See how you go. Adam 1 Quote Link to comment Share on other sites More sharing options...
