if you want all the computer stuff just remove it all from the g20 and put in the 78 just take plenty of pics and rewire from scratch AKA ( remove all the wiring in the 78 and put all the wiring for the g20 in it ) of course head light wires arnt a problem cause there on a different cuircit.

Its pritty easy to understand wonse ur looking at it i might on day convert my motor back to tbi but the truck i put it in didnt have tbi and didnt have the wiring to change over.
