    OK, I am switching my AFI fuel injection over to my new BBC and have ran into a small problem. The IAC is different. On my AFI harness it has a IAC plug that is sqare and all the wires are green. The IAC on my TB is straight and has differnet color wires, so I need to know what wires I need to splice were.

    O O all green

    O black
    O brown
    O purple
    O white

    Hope that makes sense. Thanks for the help.

    I did this before when I swapped a 350 TBI for a 454 TBI, should be like this:
    Blue/black to Black w/white stripe
    blue/white to White w/black stripe
    green/black to Pink
    green/white to White

    They may look all green but look further up into the sleeving, I think you'll find they're different colours.

    Hey, I have a leftover adapter from my painless wiring harness that sounds like exactly what you need. Interested?

    really just need to know what wires to splice together, if you had a really good pic of the adapter I could probably figure it out from there.

    Just give him the pinout...the connectors will be marked (probably A-D) where each wire goes, that should be enough to get the splices right.
