Aftermarket Cruise Control

Aftermarket Cruise Control
I bought an Audiovox CC-100 Cruise unit to go on my 89 Cummins and have yet to get it to work. It is supposed to be a universal kit but I can't get this one to work. I don't have the tach wire hooked up because I don't know where the tach hook-up is on these trucks. Is it on the alternator? Anyone suggestions? Thanks!

in 91.5 when they went to intercooled they put a crank sensor on the front for the tach.
Regardless, if the tach feed on the cruise kit is designed to work off of the alternator output from a coil, it won't work on any of the diesel tach options: neither the inductive trigger (crank position sensor running off notches in the front damper) or alternator tap. I am not familiar with those kits, however.

Did anyone ever figure this out? I have cruise control on my 89' and I'm sure i could take a look at how its hooked up if your still trying to figure it out.

I don't know about the older trucks, but in the 91-93 trucks the computer takes care of all the cruise functions. It uses the vehicle speed sensor for it's input. I don't think it cares about the RPM because the engine is governed by the pump.
Some digging shows a 88-90 factory cruise servo for "all models" for around $70. Maybe somebody with a manual can take a look and see what's involved electrical wise.
