anyone have anything??

i have a 85 s10 4X4 with the carb. 2.8. i just acquired a 91 s10 with the TBI 4.3. i already bought the swap motor mounts for the swap from advanced adapters. i drilled out some new holes for the new tranny x-member. i know i wont have a problem gettin the engine and trans. in the truck, but i am not sure how the TBI setup works. i have the ECM/ECU box and everything still intact in the blazer, and i know i will have to take it out. but what is required to get the TBI to work correctly in my old vintage s10? time doesnt matter, and i am fairly mechanically inclined...i just dont want to start pullin things apart and slappin them back together just to find out later that there was a much easier way. and i dont want to go with a stand alone unit, bc i am a college student, in the marine reserves...so i dont have the money to toss around. any input or links would be a lot of help.. thanks in advance!
