Looked at the reviews on summit and everyone hates the instructions but seem pleased with the unit itself.

Well Poo ..

Right from the start a small problem stuck it's ugly head up !

With what little handling I did to install the trick polished aluminum cruise control cover the paint rubbed off in a few areas ..
The lettering really should had been laser etched instead of painted on over a polished finish ... Would had been durable for a long time ...

Not a super biggie, but did want to see a new look on the turn signal arm ...

Customer satisfaction is a top priority with that company, I'm here to tell ya ...

I was looking through that manual and it just made me think it seems like an awful lot of trouble for something that amounts to factory GMT400 cruise control module that can be gotten out of any junkyard for $20 or less.

Is that just the Rostra retrofit cruise control stalk? If it is, you will need to have a relay system in order to get the proper signal outputs for cruise control functionality.

The column is out of a 1975 Cadillac Coupe De Ville, tilt & telescopic (Cut down, highly modified to fit) the screw-in stalk is from a early Ford Maverick ..

Reason for choosing this cruise control kit was mostly the manufacture's name ... Noted for hi-quality products ..

All components in the kit is everything that's needed to have a add-on cruise control ...

BTW ..
If you was wondering what the button is for in the tilt lever arm ..
It's for this ....

I don't know that I would go that far.... Dakota digital is known for making digital clusters, but I wouldn't say known for high quality or top of the line. They basically just remade the factory GMT-400 cruise control box. All you need is a 4 wire control stalk and the GMT-400 box and it is exactly the same thing. The GM cruise control for the entire 90's with cable throttle bodies is a standalone control box with 10 wire connector and only needs those same inputs. You need the same dakota digital passthrough sensor to provide the VSS signal(which I've seen lots of people have problems with on longevity and signal quality) and then you can have a separate light installed for the cruise engaged light using Pin 85 as a ground. Here's some pics of factory 90's box and linkage to the throttle body... which easily just transfers right onto a factory quadrajet.

Not trying to poo-poo on your install... just wanted to put it out there for anyone looking at this that it is just a direct rip-off of the GM cruise control that you can find for dirt cheap in almost any junkyard(or even on ebay or similar). The stock GM systems are VERY well known for reliability and longevity. Rostra makes a retrofit 4-wire stalk for the older squarebodies that had the single wire stalk, but you need to use two relays to convert it to the proper wiring for use in the GM or dakota system. There are wiring diagrams and instructions out there for all of this and it is a pretty common conversion.

@Bextreme04 i just did a search on here and on google, and didn't find anything about using the gmt 400 cruise control on an obs chevy. Do you know of any writeups out there?

Speaking of input ..

You must be registered for see images attach


The Input speed sensor (ISS) was plugged ..
Since a Standalone transmission controller is in use, it doesn't have a need for the ISS ..
Output speed sensor is required ..

You must be registered for see images attach


Standalone is hidden in the glovebox ...

The speed pulse generator (Came with the kit) pugged up to the transfer case cable speedometer drive ..
I'm retaining the stock speedo .

Still working great ..
The truck does have GPS built into the smart rearview mirror ..

They are stock on an OBS chevy. GMT-400 = OBS. Lots of GMT-800 vehicles used the same module until they went to fully DBW setups. The DBW setups don't need them.

Here's one talking about any 88-98 box will work by just swapping out the cable to match the original one for your truck.
https://www.gmt400.com/threads/cruise-control-module-interchange-question.51206/
Here is someone putting one in a 72 C20:
https://67-72chevytrucks.com/vboard/showthread.php?t=678828
Here's a random LS swap one talking about it:
xc_hide_links_from_guests_guests_error_hide_media

You usually find it in reference to an LS swap since the LS PCM has the VSS signal output that it needs. The reality though is that almost any VSS signal will work because it isn't looking for a specific speed, it is just looking at relative changes in the signal. In this case, he could have just thrown that US Shift POS in the trash and run an 0411 computer to run the trans and it would output the correct VSS signal as well. Then you can run different shift strategies for 4lo and cruise control and modify them however you want using free software. It would also let you see speed and transmission info live(like TFT, gear position, slip, etc...)

Being I'm not very fond of leaks, it was time for a new seal ...

You must be registered for see images attach


Well, I was in the neighborhood anyways ...

!! Great Horny Toads !!
Parts House ordered the wrong seal ...

You must be registered for see images attach


They had to do another order since it's not in stock ..
Round 2 coming up .. :chair:

Well ... Strike 2 ...
Made another trip to the parts house to pick up seal number two which was also not the needed one ...

After 3 counter salesmen tried their best to find it in their computer system ... They threw in the towel !!

And all the other part stores in my town couldn't find one too ..
Ain't that something straight out of ...
