Anybody run the Rosta of DD cruise on their swap? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I bought the Rosta Cruise Control kit, but cannot seem to get it to work. I checked the part numbers and they seem to be different between the 2 kits, although many said they were the same.

I am getting the voltage in/out, but it won't engage. The LED in the back is not lit either. Whether that is for the DD version only, I am not sure.

what is the Rosta kit and what engine / transmission are you using

That would help to know. It is a cruise control kit. L83/6l trans.

I think I figured out the issue. I am guessing the voltages for input/output to the pedal are incorrect.

Defiantly interested in cruise control with the L83 swap. One of the last things I want to get working on mine too, but use the factory switch, and not theirs...

If you work it out, let us know how it works for you.

You can use the factory switch. The problem is the voltage. The unit requires 4v on both pins, but the pedal requires 4v on one pin and 2 on the other. The Dakota Digital unit uses the same 4/2v set-up. They tell me theirs will work. I might have to go down that path.

do you have a wiring schematic?

maybe of both cruise setups, DD and Rasta...

WOOHOO! I finally got the cruise working! A bit harder than I originally anticipated, but it does work well.

what was your solution? parts list available?

Joyridin · 04-10-2023, 08:14 AM

The easiest thing to do is buy the Dakota Digital CRC-1000 cruise control. All the wires match up and you will have it working in a few hours. It is that easy to plug-n-play.

Unfortunately, I was told the Rostra kit cruise control and the DD are the same. Yes, the actual box with the electronics is the same, but everything else is different. I basically had to rewire the Rostra cruise to match the DD kit. The two kits use different plugs and a different set-up. The Rostra works fine if you have a newer vehicle running the complete canbus/brake system from OEM. The DD kit uses your brake switch (and clutch if you have a stick), and a few other variables to make the cruise work.

I thought I could save almost $200 by going with Rostra, but all said and done, I was probably about $50 ahead with no warranty.
