Interesting - my 88 C1500 came with a 5.7L and a 10 bolt 3.42 open differential.
Edit - and a 700R4

VSSB - Not sure.
As far as the wiring for the harness though, I can give a little direction. Once again, download your factory service manual for the year of your truck from the thread I linked earlier. Find the pinouts for the PCM connectors, and the pinout for the 4L80E transmission wiring harness plug. Run all the wires for the pins in use at the transmission plug, and connect them to the appropriate pin at each plug.
Another thing to consider... This isn't the route I would go personally as I like having OD, but you could always swap in a TH400 and avoid all the electronics.
i did download the service manual, and found several youtubes on the rewire to trans, the VSSB trips me up.
The TH400 option is interesting, although since i drive the truck everyday I also prefer the OD. A 400 would render my truck to off-road /fun only truck, i fear, because of the drop in mpg
im running 3.42 gears fwiw
well, maybe I'm shortsighted on the mpg drop.
