    Default Wiring diagram for review, comments


    I just purchased and received my smart-wire and have been diddling on paper w/ wiring schematic for my application and request comments / suggestions from Racepak and forum members.

    1. Smart-wire
    2. IQ3 w/ logger
    3. FAST XFI / XIM (ignition)

    I attached a schematic which I created for review; is this correct or is there a better way to achieve full potential of my IQ3 and Smartwire??
    Is there a way to eliminate the relay that powers the XFI module?? I sure would like to power directly from my Smartwire.
    The FAST schematics are dated 2007, well prior to the invention of Smartwire or any other power management system which I am aware.
    FAST XIM (ignition) only mandates that the 3amp supply be connected directly to the battery, the 30amp from a switched source. My schematic is this way, 30 amp powered by Smartwire; see any problems??

    Please Advise

    Most Appreciated

    I would use ground (earth) to feed all the switches, that way you dont need to have a fuse or wire it back to the battery. Just program all those inputs to look for Ground.
