why not go awd? since you have everything, lemme know if you decide to sell that AWD transfer case.

my thoughts exactly. that would be unique and thats why we do this. if you've got the whole truck use it.

You're gonna find that EFI is just as easy as doing the carb setup; after the first one, it's easier.

You can reuse the harness, remove all the extra wiring you don't need, gather all the grounds and powers and connect it all correctly; there's more to it than that, but you'll figure it out.
Be sure to get the TAC module; small black box bolted to the driver's side firewall and the foot pedal, with all that wiring as well. Take your time on all that part because if you mess up on it, you'll spend more time fixing it.

There's info on what fuel connectors to use on the site.

I believe you'll need to swap out the rear shaft in the trans and get a tailshaft assembly; someone else can chime in on that.

good luck on the conversion, you'll like it.
