350 Swap, wiring

[Chevy666]

Hi,

So i got a hold of a 1996 5.7 Vortec together with the 4L60e and transfer case so I´m doing a complete swap but I stumbled on the wiring stuff and thought maybe I could get some help/input:

I have the Black box and engine fusebox together with the wiring for the motor,transmission and transfer case. So it should be "plug and play" but then it´s the bulkhead, what wires from the bulkhead in the vortec wiring should be splised into the TBI harness?
I´m wondering if I´m forced to make two standalone harnesses, one for the motor and one for all the accesories in the truck (wiper, lights and so on).
But should it be enough to find the ignition wire from the TBI harness and plug it in the Blackbox for the motor to work?

Thanks for all the help I can get!

Oh and the motor is going in to an 1989 TBI K1500 4x4

Easier to swap dash, harness and all. I prefer the 95-96 dash but whatever you can get complete
