Cruise It's all hooked up an don't work. I have Dakota digital vss signal on tcase it's a pass threw deal requiring 8000 ppm . I had ecm programmed an I am not sure if it's rt or not. Have had some issues with tuner
I know can do it myself but not sure what to change. My paper work said thay no known signal converter does 128000. So my ecm will need programmed to 8000.
I did have a guy ride along with me that's fairly knowledgeable with ls an tune . He go my computer to read my speed an it's accurate. The guy is traveling so I am stuck for now. I saw on the tune where it says 128000 but wasn't sure if I should changed that to 8000 or not.
Can you leade in the right direction?

Im not sure it will work with an 8000ppm signal or not. The factory module is looking for a 4000ppm signal, but I would think it should work to a point since it would just think you're going twice you're actual speed. If your tune is set to 128000ppm, then theres no way the cruise will work with that, that is generally for traction control. Have you tried setting it at a lower speed, say around 25mph so that the cruise thinks youre going 50mph? If you try to set it at 50mph the cruise thinks you're going 100mph and I dont believe it will work that high. You may need a signal modifier to get the signal to the cruise module down to 4000ppm.

Im still thinking its your PPM is too high. Not sure if a Dakota Digital sgi-5 or something similar would work to modify the signal down to 4000 or nor, but you might try calling them and asking.

Also, just to be sure, you do have the VSS wiring hooked to the PCM and not straight to the cruise module, correct? If so, what does the MPH look like on a scanner or your HPTuners while driving it? Is it close to actual?

Cruise control Yes it is to the computer an speedometer on tuner is perfect. My only delma is I am not sure what the vss output is to be set to on tune. Every1 sells a vss signal pass threw device an no one will tell me what to set tune to.

OK, so if the PCM is seeing the correct MPH, I would "think" that the cruise module would be seeing the same speed and should work. You have the Speedo wire coming out of the PCM hooked up to the cruise module, right? When you say it sets from 47-55, what happens when you set it and use the accel button to try to go faster? Is it shutting off, or just won't go any faster?

Cruise control Huge thanks to ls1nova71. I guess I missed something but I hooked the vss out on module to the speedo wire out of the pcm. An Yay it works just like it should. I had it hooked up to abs side of the computer reprogrammed it to 8000. The speedo is programmed for 4000 what the module needs. You are so help full. Thanks again.
Maybe I'll see some of yall in Sema or pri

I have my speedo, and reverse lockout solenoid box both coming off my transmission signal, as well as the cruise unit. It will come on and work, accel, decel, etc, but only for seconds to maybe a minute or 2, then it disengages. Do you think I have too much using the one signal, and would a pullup resistor possibly help? Thanks.

Which one of these wires or PCM wire turns on the "cruise" light when the cruise is engaged?
I have dakota digital gauges with a built in cruise light and need to know which one can operate it? I'm sure it will be a wire that is showing ground when engaged

Update: I spent some time with my truck and the multimeter today and figured out the "cruise engaged" light. Turns out the J terminal coming out of the module supplies a ground when the cruise is set, so all you have to do is wire your light to the J terminal on the ground, and the other side to an ignition on power source. It works PERFECTLY! It works exactly like it should, doesn't come on until you're at the speed that the cruise will set and goes off whenever the cruise is disengaged by either hitting the brake or turning it off. Also comes back on when resume button is pressed, and goes off when the coast button is pressed, but when you let off of it and the cruise engages again, the light comes right back on.

I'm just messing with you, man! I know how it can be hard to find information when the threads get to be really long. You did see my answer in the quote, right?

That was my 1st thought, so I went to the JY and grabbed another one, and it does exactly the same thing. That's not to say that both JY boxes can't be bad, you never know with unknown used parts.

See if this helps 
[QUOTE=1976CamaroGuy;19010278]Which one of these wires or PCM wire turns on the "cruise" light when the cruise is engaged?
It's the other wire coming out of pcm. The engage wire. The 1 the don't need to be hooked up to work. It should turn light on
