There might be different colors in your harness since radios vary from model to model. If you are not sure about color codes, contact your nearest dealer or manufacturer. Fortunately, most manufacturer’s are trying to use the same wire codes. With minor variations, the second table applies to most aftermarket head units. The first table covers older Pioneer radios (up to 1998).
