Okay, i forgot that about the 4x4s. Basically i just need to know what wire behind the glovebox is used to run the speedometer. I'm keeping the 4L80E in my C3500 6.5, but since i've swapped to mechanical injection and a aftermarket controller is running the speedo, i dont know what wire to use for my speedometer output..

i forgot 4x4's use transfer case speedometer inputs.

Yes, then it goes to a VSSB box, Vehicle Speed Sensor Buffer box or something, i have the schematic, just wanting to make sure before chopping the harness... haha.

Should'a got a 4x4.

i recently picked up a 98 k2500 8-lug truck with a NV4500 for parts. i mainly needed the bed off it. the engine is missing but the rest of the truck is complete. I thought of selling off parts that i don't use.. but after reading this, im wanting to swap the 5spd into my 94 with a 4l60 trans later on. thanks for the info.. now i've got some planning to do.

Are there any other bellhousings that will work with the NV4500 besides the one that it comes with from the factory (ex one from a 86 1500 350 with a 3 spd., a 79 Camaro, Etc.)
