cruise arm has a momentary push button switch in the stalk end , would work fine and the wiring isnt really a problem , take a look at the cheesy wire they give you on the line lock switch
if your cruise is still in the car rather than go cutting harnesses , unplug the wire under the dash , get a connector from junk yard and then find the two wires that the button connects to
the cruise wont be usable but the line lock will work just fine
rather than install the supplied switch on the shifter like i see most do ,an easier and just as stealth is install it on the tilt lever , unscrew it and slide the lock switch on the arm , much harder to see it there and easy to get at , easy to run wires into the dash and no wires getting caught in the shifter, and you'll still have cruise
