We’re going to explain wiring diagrams and color codes for JVC car radios such as the double din JVC KW-M150BT and KW-V250BT, and the single din JVC KD-SX26BT. All this info is taken from official user manuals.
Despite the fact that many JVC stereos share the same wiring diagrams, we recommend finding the original manual that corresponds to your specific model in order to make sure you’re using the right information.
