The Opel Manta was a rear-wheel-drive sports coupé motor vehicle built by Opel from 1970 to 1988. It was based on th Opel Ascona. The Manta was normally equipped with a 1.6–1.9 litre CIH engines, although in Europe a small 1.2 litre motor was offered. All Mantas sold in the U.S. had the 1.9L and larger heavy duty radiator (an option on European models). It came with either a 4 speed manual or an optional 3-speed TH-180 automatic.
The following electrical circuit and wiring harness diagram apply for both Manta and Ascona. The Diagrams are based on the 4 basic sections of the wiring harness as it is shipped from the factory. They are the Front Section, Dash Section, Column Section and Rear Section. They are to help guide you as to which wires are in which section of the harness. For each section compare the wires in the harness to the layout of your car and its wiring harness. If rewiring a classic vehicle, review the original factory wiring diagrams and compare the two diagrams for circuits not in the EZ Harness, or circuits that are in the harness that you will not be needing.
