Under the dash where the cruise switch wiring plugs into the underdash harness you will find there are 4 wires in that connector. Basically you would need to cut the gray, dark green and dark blue wires there and wire them into the wires provided in the LS harness. The colors will probably be similar, but if they aren't, they should at least be labeled. Gray will go to the 'on/off' wire, dk green to the 'resume/accel' and dk blue to the 'set/coast' wire. The fourth wire will be pink and needs to be hooked to an ignition source so that it has 12v whenever the ignition is on. You "shouldn't" have to do anything with it, but you never know what has been done to a truck in 35 years, so you would have to verify it to be sure.

Perfect! That's what I like to hear. Thank you for the knowledge
