Many people wanting to install a new replacement radio in their vehicles usually become confused when professional installers and/or salesman inform them of these separate snap on wire harness adapters. A common misunderstanding for these people is that they wonder why they need to purchase an additional wire harness when the radio either has wires already attached to the radio or a wire harness is already included with the new replacement radio. The wiring on the rear of new replacement radio is designed in one of two ways: either the wires are connected internally to the electronic circuit board and then extended out of the rear of the radio, or the radio is designed with the wires attached to a small plastic wire harness connector which can be plugged into the rear of the radio. Most modern radios are designed with a separate wire harness. This allows the wire harness to be wired to the vehicles speaker and power wires without having the heavy radio attached. This also allows the radio to be unplugged without having to cut the wires.

CIRCUIT TEST A-1: MALFUNCTION INDICATOR LIGHT (MIL)
With ignition on, PCM energizes main relay. As PCM is supplied ignition power, MIL illuminates. After engine starts, MIL turns off if no malfunction is detected. If a malfunction is detected, MIL will remain illuminated until system is repaired.
1) Turn ignition on. Observe instrument cluster warning lights. If all warning lights illuminate except for MIL, go to next step. If no warning lights illuminate, check for blown fuses, faulty ignition switch, or poor connection at instrument cluster. Repair as necessary.

Please read the installation procedure listed below as it will save you time (and possibly parts) in the long run. After installation…enjoy! Caution! Be aware that E-PROM’s are static-sensitive devices, and so are the chips in your control unit. Avoid replacing chips in high static areas, and avoid touching the pins of any integrated circuit / E-PROM.

1. Open hood and remove the rubber seal laying on the top edge of the firewall. Remove the plastic raintray and locate the control unit. It is located on the driver’s side on Golf and Jetta 2 models, the passenger side on Passat and A3 models.
