It wouldn't be the first time I was mistaken, but, you know, I have yet to actually take apart a '92 or '93 that DIDN'T have cruise already.

All I know the '91 column that I have in the carhauler DIDN'T originally have cruise, yet the original '91 wiring plug has the 4 (maybe it's 5?) wires in the clockspring plug, instead of just the 2 for the horn.
The dash/column wiring in the truck now is a '92 one and I do have 2 issues that need tracked down.
1 being that the cruise doesn't work, the other is no hazard signals, though I have EVERYTHING else, even speedo, all guages, dash lights, park, headlights, dimmer, all turn signals, preheater controls, dome lamp, cargo lamp, key switch light and brake lights.
Even an annoying keybuzzer.

Mark.
