converting my 99 f250 from 5.4 to 7.3 need help

ok here is the deal... i got most of it down.... to describe it all the parts came from a 99 f250 lariet and mine is a xlt.... i had power window and locks no keyless entry... mine is a crew cab and the other one was an extended cab.... so i am tryin to figure everything out but i have a few problems... when i replaced the wiring harness and all that i left my interior harness the one that runs the doors and dome lights and all that.... i replaced engine harness, tranny harness, dash harness.... to start off with my dome lights would not work unless i pulled it back into 4wheel drive... i found that to be a ground wire that was in the other cab harness due to having an extra relay box for what i imagine was power seats and the keyless entry stuff.... so i spliced that in and grounded it to dash with other ground wires... so dome lights are fixed... next... i turn my hazards on and now my cab lights flash and instrument cluster backlights flash... if i turn my turn signal on cab lights flash... if i turn my parking lights on and hit turn signal bulb lights up buzzing from flasher but no blinks.... not even the park light will flash.... then if i turn key on my supply pump will not come on and the wait to start light will not come on........... so i am kindof lost sounds like a ground to me but i have went over it time and time again and cant find one that is off or missing.....
