Harness adaptor to connect your new car audio unit to the car's original wiring loom. Without these clever little adaptors you won't be able to hook the new wiring up to the old, so we carry a wide range to fit most makes and models of vehicle. We have Peugeot harness adaptors, Ford harness adaptors, Citroen, Honda, Vauxhall and more. So if you are looking to upgrade the stereo system in your car, or simply to replace a broken radio, then don't forget to pick up a harness adaptor from us first!
