I've got a 98 chevy c1500 4.3L and am doing a lq4 swap. I want to put cruise in it and need to find out what i need. I seen the cruise box on the firewall of some in the junk yard. Is that all I would need is that box, wiring, and turn signal with cruise or more to it than that? And since i'm doing an lq4 swap can I use the cruise from the 98 year or have to use from the motor year truck?
This is when DBW is a good idea for a swap since you get the cruise control built into the PCM.
Well thats what i'm wondering. I am going dbc, but my style truck there is a cruise box/servo outside on firewall, it would take 10 min to get it off. Not sure what else is there in the system, if the pcm controls cruise too or just that box.
99-02 trucks use the same cruise system as the OBS trucks, just a different length cable length from the module to the throttle.
Install a OBS turn stalk with switch and the appropriate wiring to the module and you will be good to go.
gotta get all the wiring for the cruise thats inside the cab, too.
Sweet, cause the yard only wants $15 for the cruise module. Ok so i'd have to get the turn signal stalk off, have to figure that one out. And i'm guessing the wiring your talking about goes from the stalk to the module, and fuse box. Am I missing anything?
Why couldnt you just tap in the vss signal that your cruise box needs from the genIII ecm?
It will come from there. His truck wasn't originally equipped with cruise, so he has to add the components.Quote:

Ok what do you mean by adding components? I i use the cruise module and turn signal from my year truck it should all plug right up. Is there something else I have to add besides a longer cable?
You are adding the cruise module and turn signal switch right?Quote:

Ok he made it sound like more. Thanks. So the cruise module controls pretty much the cruise. Whats the talk of the pcm controlling it? Is that just on newer styles or something?
vehicles with the electronic throttle body, the PCM controls the cruise since it can so easily. There are no provisions on the ETB to hook a cable so the cruise had to be internal to the PCM to handle cruise functionality.
He was talking about the VSS signal coming from the PCM.
So, the '07 and newer trucks cruise is controlled through the PCM ? I bought a harness with all the electronics from the "new" body style '07 Silverado, but it did not have the TAC module that others had mounted on the firewall, I went nuts looking for some kind of module that connected the pedal to the PCM........the only one I found was under dash and had 3 connectors running to it........I needed the newer 58x setup because the LS2 I have is set up with the same..........how complicated is it going to be integrating the '07 cruise to my '93's system???
All DBW trucks have the cruise controlled through the pcm. I believe 06+ dont use a TAC module at all because the TAC is taken care of within the pcm. Integrating your cruise should be as simple as the others - just a couple wire hookup. Someone will come along soon and clarify/correct my post.
thanks........
