    Default GM HEI Remote Coil Wiring

    Hello everyone. I'm looking for some confirmation on how to wire up a GM HEI remote coil.

    Based on the information pictured above, I have come up with the following.

    Grey connector, Pink wire (top left of coil connector) - Goes to switched ignition. Hot in run/crank.
    Grey connector, White wire (top right of coil connector) - Goes to the loose yellow wire for tach input to ECU.
    Black connector, Pink wire + Pin (bottom left of coil connector) - Goes to the black wire on the two pin connector for the distributor.
    Black connector, White wire C Pin (bottom right of coil connector) - Goes to the yellow wire on the two pin connector for the distributor.

    I'm confused about the two pin distributor connector that came with my HP kit. The instructions don't mention the black/yellow wires. I'm just going off diagram 10 on page 20.

    Thanks Danny for the link to the updated manual. If I'm looking at this correctly, the white wire "C" goes to the yellow on my connector. The pink wire "+" goes to the black on my connector. The loose yellow wire is not used in this application.

    The illustration in the Holley EFI Wiring Manual is very explicit, and has your exact same ignition coil. Disregard the wire colors, and follow the diagram.

    The loose yellow wire is not used in this application.
