if the multi switch was replaced, the main cruse control motor should still be hanging of the firewall or at least its mounted there on the 1/2 tons right beside the windshield wiper motor. That would be the first thing to check out. If it is not there or doesn't look like one has been mounted there (should be 3 bolts) then I would be guessing your truck never came with one. You can go aftermarket and get the set up. Or search your local salvage yard for all the parts.

IIRC all 6.5L PCMs have cruise capability, as it is controlled directly from the PCM to the injection pump electronics (94 and up). 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.

:eek:

Whoa! how bout going the easy way first and pop the hood open and look for this hanging off the firewall:

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.
