    Default Multi-Map Key Switch

    Hello everyone. I'm new here and new to the Holley EFI system. I have a Holley Dominator on a modular Ford and I'm running Drive-By-Wire, but I also want to run the Multi-Map key switch, but both the grounds for the Multi-Map key switch are already being used by the Drive-By-Wire. What ground do I use for the multi key switch? Thank you very much for any information you can provide.

    Any of the ECU grounds should be fine.

    Is there a version of the switch with a handle instead of the key?

    No, not from Holley.
    However, if you only need two Global Folders, then a simple toggle switch is all that's required.
    Normally open is the regular GF, and grounded (pin B17 - P3 connector) is the 2nd/alternate GF.
