    I'm putting a used classic FAST on my big block mopar, it's setup for IPU

    my injector harness is stock GM small block according to the wiring diagram in the instructions. According to the chart, BB mopar has the same firing order, but the wire colors are supposed to be all different than sbc/mopar sb. LT1 and BB mopar share the same wiring. If they have the same firing order, I don't get why the wiring order is different?

    Additionally, if I'm not using the seq. function to start with, does any of it really matter?

    Thanks

    FAST tech guy says don't worry about the injector harness colors, as long as the firing order lines up with the lettered terminals I'm good (which they do). He didn't really have an answer for why the manual had that chart, since it's old at this point. Could have just been a misprint I suppose.
