Small update, yesterday I mocked up my fuel lines and got all but the trans connections and loose wires connected on the standalone. Turns out the starter that was sent to me doesn't fit, it looks exactly like the starter from my 95 so I need a new starter also.
I also got my throttle cable all hooked up...WOT for the 5.3 feels to be about 3/4 throttle the way the pedal came from the factory so it should be fun to drive in the rain
Edit: and yep the throttle blade does close completely
