Well those wires coming from the resister box are not grounds, they are power. Learned that the other day from cxcivic. The wire colors for the obd1 are yellow with a black stripe. The colors that go to the ecu brown, red, blue, yellow. The reason for the different plug for the dizzy is the dizzy has extra sensors in it. All will match up except 2 will be open. Those are the ones you add. Think thats right from the things I've read. Check with Neal (cxcivic) to make sure.
