I would remove your steering column trim and see if there are wires on the vehicle side of the multi-function switch connector that do not have mates coming from the switch. If so, I'd guess they're the cruise wires, and replacing the MF switch will make the cruise work.
IF it was 93 or older. 94 and up have no throttle linkage, fueling is controlled electronically.sledog;1550659; said:

If you see that. Its your cruise control module. If you don't see it, I would be guessing the truck never had cruise from factory.
