This system consists of an electronic control unit, a distributor with a reluctor and magnetic pick-up (4-cylinder engines use a Hall Effect pick-up) and vacuum advance, a coil and a ballast resistor (except on 4 cylinder models).
The V8 and 6 cylinder engines use a control unit with a 4 pin connector. The 4 cylinder engines use a 5 pin connector on the control unit. All 4 cylinder engines have a distributor with a 3 wire connector, all V8 and 6 cylinder engines use a 2 wire connector at the distributor.
