4.3 tbi swap to 5.7 tpi

Ok I'm sure this has been done more times than I am old and my brother said this was a good place to get help so here is what I got, 1993 Chevy c1500 2wd with a TBI 4.3 backed by a turbo 400 (out of a 89 suburban with a big block) stock 3:08 rear end, I'm want to use a TPI out of a (89-90s?) Carmaro (it doesn't have the 9th warm up injector) the motor is a 94 5.7 ( its out of a k-1500 4wd ) both the 350 and the TPI need to be rebuilt and I do not have the wiring harness or the he ecm for the TPI, so what's the easiest way to make this work, would love to use fuel injection but never set one up always have done the carb swap
Thx for any help guys
