cruise control conversion I would like to install a 4th gen cuise module into my 1st gen with ls1 ( i plan on using a 3rd gen column) any input would be appreciated. I would like to know if the module can be controled independently or will it need to be ran through the pcm.
thanks
I posted this earlyer but it did not show up so if it shows up twice I apologise.

after looking into it, and at the physical size of the components, i ended up buying a aftermarket cruise control box, and having someone braze a LS1 cruise control cable to the aftermarket cable...
nice and compact, other then the brazing, it was a easy install.. and it used the GM switches...

Since we're on the topic...
I hooked up my factory CC module up per the wiring diagram I got but unfortunately, it's not working. I need info also... where do I start looking for the problem and how? I'm using momentary switches rather than the GM stalk. Could that be it? Help!

It's MUCH easier to get the factory type cruise control going if you trade your LS1 cruise module for one from around 1991-1994. They are the exact same size, same connector, and same cable, BUT they have no PCM interface. I've used these units on swaps and they work great. The easiest ones are from the 91-92 Caprices and trucks. The only inputs are a brake switch, VSS signal, power, ground, and the wires from the column switch.
After that they add a second brake switch input, and then more and more PCM interface making them more difficult to get going.
Mark, pick up an earlier module, plug it in instead of the one you have, and as long as you have your momentaries wired up properly, you'll have CC!
Otherwise it pretty much requires a scan tool to see what it's not "happy" with. Cruise control doesn't need to be that complicated.

The factory cruise controls are much nicer and more reliable than aftermarket. They also have the 'tap-up and tap-down' feature in one mph increments which is real nice. I don't know about the LS1 cruise modules, but the older modules work as I describe below.
If you have the wiring harness installed and powered up properly, here is how I test mid-90's Caprice cruise control installations (I do a bunch of these installations in retired Police cars) before plugging the wiring into the module. The way I install the cruise control systems...the PCM isn't involved at all.
Using a test light secured to a good ground, and the vehicle key in the RUN position, here is what you should get when you probe each of the pins in the connector:
PIN A Cruise Control switched ON
PIN B Set/Coast
PIN C Resume/Accel
PIN D Brake pedal released
PIN E Ground - no light
PIN F Key in RUN position
PIN G Brake pedal depressed
PIN H no connection
PIN J no connection
PIN K Vehicle Speed Sensor (light will be somewaht dimmer than the others)
If the wiring harness is installed properly, the results should be as above.
Hope this helps out,
Gary

(figured I would post this here also)
Need a little help.....
I'm in the process of finishing up my Fast XFI swap in my camaro and I want to use the "old" 1991-1994 F-body (is the 1991-1992 caprice/truck cruise control the same as the 1991-1994 F-body version?) cruise control.
Could someone give me the pin outs for how to wire this up (ie: the pin out order on the modal its self)? I'm still using the stock F-body steering column (with its stock wires in place) but ALL the "intermediate" wires in the car have been removed (full rewire).
Anything I need to keep in mind?
Thanks

ok....update.......
I went to the dealership this afternoon in search of some part numbers and this is what I came up with as far as F-body Cruise Control modules:
1990-1992 = 25111869 ($192)
1993 = 25140793 ($89)
1994-1997 = 25140793 ($89)
98 = 25177447 ($110)
99-02 = 25315081 ($110)
so WTH is going on here?
this is why I really need someone to give a little more info......the part numbers seem to say there is one module for 90-92, one for 93-97, one for 98, and then one for 99-02? WHICH ONE DO I USE?!?!?!?!?
