In the instructions for installing the control linkage, they did not list the 6.2L Diesel engine, only gasoline engines. So I called the mfg.. to see if they had a recommend way of installing the linkage to the diesel engine. They where of not help as if they didn't intend to make it work on a diesel engine. And when I finally told them it was for a Hummer, they where of even less help. Now I know why they did not have it in-stock, because they didn't know what was need for a Hummer. Or maybe they are the OEM for the Hummers now and have some sort of contract with AMG, like my mirror I got that is used by AMG.
Anyway, after looking over the linkage I figuring what and how I was
going to do it.
The Controls: JCW sent me a small control panel that is surface mounted and could be placed just about any where. That part number is 204-4110, Click here for picture of the controls.
The Cruise Control was ordered from J.C. Whitney, P/N 78DN7618F.
The Mfg. is SCS/Frigette and their P/N are listed below:
- SCS 4365 Cruise Control $229.95 (4/99)
- 208-3609 Speed Sensor
204-4110 Switches - 2 button, and on/off sw. (option)
Note: The kit also came with a speed
sensor that connected to the odometer cable, and normally the 93 Hummer's
have this, but I replaced my speedometer with an electronic one because
the cable was always giving me problems. So instead of using this sensor,
I am using 2 magnets and a coil that are a part of one of a other speedometers
that I installed. If you are installing on e 94 or newer Hummer,
you would normally connect the blue wire the back of to speedometer (sig)

|Control cable mounted. Note: I did not use the crimp to hold the cable in place that came with the kit, instead I used a small hose clamp. The hose clamp I figured would hold better then the crimp and could be adjust if needed later.|

I have a few more pictures to come - Dash Control, Servo Controller, and other controls that did not fit my Turn Signal switch.
Operations: This cruise control held the speed better then
any cruise control I have ever used. Using a GPS System to track
the vehicle's speed, this unit only varied about 0.25 mph on the highways,
Up most hills it was right on track all the way. You cannot ask for much
better. My factory install one on my 96 Suburban varies about 1 mph.
Another installation with a newer version unit: This one has a little more info with the installation manual then mine, and the switches are also different then the ones that came with my unit. Mounting hardware for the throttle linkage was also a lot easier and simple. Mounting hardware for the servo was also better and worked out great here on Chad's Hummer as seen here. The installation was for the most part quick and easy, but we had a little problem with the speed sensor that mounted to the speedometer cable that would not come apart, and when it did, the threads where all wasted. But we got it to work and on the first test run, it ran great.
This unit that was ordered for Chad's Hummer was ordered from Aaron Air Dist, in Miami Florida:
