Default wrangler JK, 5.3 no throttle dbw

Hi guys, i just finished my 5.3 wrangler swap, the jeep will start and idle fine but i cant get any throttle responce, its like i have no pedal.... my 2004engine came without a Tac or pedal, so i bought them from a local scrapyard...

to my knowledge all part numbers of tac and pedal are correct, i have a 9pin tac and a 9pin pedal, also my TB has one socket.... i cant figure out what i need to do to get it to run????

i have a p0120 code, so im guessing the problem is is from the TB? im not sure though....

how do i make sure i have the right TAC/Pedal/TB( if thats my problem), are the TAC/pedal different in 2003 than in 2004?
