    EFI wirers?

    I'm running a carb not an EFI and I have an AL-6 MSD box and a MSD distributor. I have two wires with the Ron Francis wiring harness orange and blue that are for an EFI. Should I run the orange one to the coil or is this necessary.

    Thanks ED.

    The orange wire in the RF EFI bundle is simply a switched 12v wire. If you need one for your MSD components or coil, use it or use it for any other 12v switched need.

    Light blue wire is +12V ONLY at ignition. Good for triggering a latching relay, but generally not used for carb.
