Wiring harness fuel injection 79-85 reproduction FIAT 124 Spider

The wiring harness for the BOSCH injection system of the FIAT 124 Spider includes all connections/plugs, except for the plug of the fuel pump relay. You must remove this from your existing wiring harness and reuse it, or plug the contacts directly into the fuel pump relay. The contacts are labeled with the numbers printed on the BOSCH relay.

Before purchasing, please make sure that the wiring harness is actually the cause of the existing problem on your vehicle. Based on our many years of experience, there are various reasons why a vehicle may fail to start or run poorly. Common causes include a defective control unit or a faulty air flow meter. These and other possible faults should be checked by a qualified local workshop.
