Motor swap

Ok I have a 1994 jimmy 4.3 vortec V6 with about 130,500 miles its ran rough since I bought it and I just narrowed the problem down to the CPI which is runnin close to $300 (everywhere Ive looked anyways). Now I can pick up a "totaled" (hit on the passenger side insurance company totaled it, no damage to the motor) 1995 jimmy with a brand new crate motor with 15,000 miles on it (4.3 vortec) for about $300. My question is will the 95 motor fit the 94? Now Ive read there will be some electrical differences but as long as I get all the wiring harnesses and everything Ill be alright, and like I said ill get the whole truck (minus the driveshaft and gas tank).

Motor will bolt right up.
But 95 was in the change over years on electrical/computer system.
About 3-4 different setups.:screwy:
Keep the same electical /sensor stuff as you 94 has and you will be OK.
Is the 95 the 2 wire cpi inside front of intake setup or the 12 wire into top of intake?
