Can I ask you what is that part an whats it do an what year make an model truck?
Transfer case 1996 3500 borg warner 4401
3500s that the 4401 came in have another sensor in the front diff to get it in sync before engaging. im not sure if that will cause you an issue or not with what you are trying to swap it into.
People have done it. There is a thread about it on this site but the wiring diagram pictures are gone. I have most of the 96 harness and it will plug into my 99 but there are 4 wires that were cut and I have no idea where they should go.
