94.5 runs but will not accelerate!

I have a 94.5 f350 that we swapped a 7.3 into. we have it running now but it wont accelerate and will only idle. the motor is a 94.5 the wiring is from a 95, underdash harness 95, pcm 95. We used a test light and there is no power to the throttle position sensor. the ivs was also jumped but no luck

I also have three large plugs that i cant figure out where they go. these are tied in to the underdash harness near the throttle pedal. i have looked at a 96 and a 97 and neither have these plugs. what are these for? thanks

I dont remember exactly how the sensor works but do you have power across it when you press on the pedal?
