    HEI connections

    First post here. I'm putting a Performance Distributors HEI on my 68 SDV, and need some help figuring out where to run the connections.

    How do the following wires connect to the new distributor:
    The 18ga. black/white wire from the AC compressor clutch solenoid ?
    The 18ga. yellow wire from the R post on the starter solenoid ?
    The 20ga. white wire which runs to the ignition switch ?

    Thanks.

    Re: HEI connections

    For HEI, you need 12 volts with ignition on & cranking.
    The the 20ga. white wire which runs to the ignition switch may not be hot while cranking.
    The 18ga. yellow wire from the R post on the starter solenoid is hot while cranking, but I think the voltage is cut down.
    I'm not sure about the 18ga. black/white wire from the AC compressor clutch solenoid.
