D100 Wiring diagrams/pinout
The basic circuit. This omits the brown bypass circuit which goes to the bottom right terminal of the ballast. That provides system power during cranking. Notice the upside down "U" at the bottom of the ballast. That indexes the ballast as the two resistors are different. Once again, the right side, the coil side, is same as for points. If you have a 4 pin ECU you can unhook the left side and it will still run.
ECU !!!MUST!!! be grounded
