hey guys i am 15 years old and thinking about putting a 3.9 isb 170 cummins with an Allison 1000 in my 1993 dodge W150. I just had a few questions about how to do the swap like how i would connect the engine harness into the existing truck harness so that all my gauges and other electronics in the cab will still be functional and working. also this is a 4wd pickup and the trans is only 2wd. I've read some things on how to convert it to 4wd but i don't have any idea on what transfer case i should use. the truck originally had a np241d in it so would that match up to the allison?
