Question about Cars & Trucks
I need a color code for the radios wiring harness so I can install a new radio in the car.
Hi Caleb, There is a way of identifying the cables without the colour codes. Make up a test lamp and get an almost flat AA or AAA battery cell. The music system has an earth connection which you can identify by looking at where it is connected (onto the chassis of the set). It has a constant power supply and another which is controlled by the ignition switch. If the set you're fitting has automatic night and day illumination, there will be a connection operating from the panel lights. The constant power supplies power for the memory. First identify the connection which when connected is controlled by the ignition key. Once tested identify the cable which remains 'live' even with ignition off and mark it. With the AA or AAA battery cell, test each pair of cables by connecting one cable of the pair to the + and swiping the other cable of the pair across the - side. The speaker being tested will be identified by a 'thumping' sound. Mark each as to its physical location in the vehicle. Connect each to the correct output. and when done you will be left with the antenna connection, which only fits one place. Identify the memory power cable, the illumination power (becoming live with the park lights) and the power output from the set to the power antenna (if fitted.) Make the final connections. Record the access code somewhere safe and fit the set into the consul and happy listening. Regards John

did u know that they make a harness for your car that plugs into your factory harness and then adapts to your aftermarket radio? for the lights, you have blown the interior light fuse, it may be the same fuse as the cigar lighter.Below is your radio wire colors and what they do.

the easiest way to install a new radio is to get the wiring harness adapter for your vehicle it runs about $25 and then you do not have to cut the factory harness. the wiring codes will come with the new harness and is just matching up there color code to the new stereos color code.
