1976 fuel injection questions Options

[914incali]

Picked up a 76 out of texas that had been converted to single carb that just doesn't run very well. I decided to convert back to original FI, essentially everything is gone and I am working on understanding the system. I guess my first question is where does the fuel pump draw power from? there is a single black wire underneath the fuel tank that has no power to it but all the relays have been removed and Im waiting on those from pelican

My butterfly plate has a hole in it with a screw and nut that looks original because the bottom threads of the screw are peened to prevent removal . I'm not really sure about that as Ive seen some with and with out holes but never the screw in the hole .

The butterfly should have two screws that hold the throttle body to the lever. Most TBs have an additional hole to allow some air in. There are some butterflies that don't have the additional hole. It sounds like someone blocked the hole on yours using a screw and a nut to compensate for a high idle (vacuum leak).
