column may not fit from van to truck as it might be too short. 86-93 trucks have 50 way bulkhead, i think. just a matter of changing/adding/lengthening some wires. i am playing with changing some 81-85 over too 86-93 stuff. get a factory service manual or i can take a pic of the bulkheads from mine if needed. van may be totally different. pm me if you need something/pics. i will try to help you if i can.
