Ok, I got it working!!! I needed to replace the SIR coil. Actually, I just replaced the wiring on both sides, though i don't really think this is ideal.
It's a funky setup - a little noisy, but it works well enough.
If you want to add it, here's what you need for the factory setup. I don't know if it changed with ODBII - so get the parts for the side of '96 you're on...
- The steering wheel switch. Make sure you get it for YOUR wheel, they're different for airbag/non airbag types.
- The back cover on the wheel - ditto on above, plus color :)
- The 'SIR coil' for airbag cars. It's got two cables behind it attached - one for the cruise/horn, and the long airbag. You *NEED* a steering wheel puler for this!!!
- The cruise box - I think there's a few rubber groments for mounting it, so check and make sure you've got all the hardware. Don't forget the thingie on the gas pedal. BTW, you can disconnect the cable easy - just pull the coller and unscrew. This makes removing the box without breaking the cable easier. Trust me :)
- The clutch switch, if you've got a manual.
Tools:
- 8mm, 7mm, 5.5 (7/32?) nutdrivers, and a 10mm socket and como wrench.
- Steering wheel puller.
- Pilers to pull those %%#$% CPAs on the airbag crap. Not needed if you've got no airbag.
Before getting the parts:
- Wiggle under the dash, and look for a flat 1" wide plug somewhere along the wiring harness over near the gas. It was taped up on my car to the wiring loom - pull gently and it comes down. The plug's black with a red (on mine at least) thingie stuck into it.
- If you've got manual, check that gray plug for it is up over near the top of the clutch pedal.
- Check the fusebox. If you've got a 'cruise' fuse, you probbably have the above two, too.
I got everything I needed at a U Pull it for about 20. Your mileage may vary.
Installing everything - do the underdash crap first. Pulling the kickpanel off helps unless you're a contortionist like me. Remember to adjust the switch and unplug the airbag down there if you've got one.
When you hook the gas cable up, don't tighten the thing too tight or it'll pull on the gas...
Then do the steering wheel junk. You'll have to fish the cables around which is a pain.
Once it's all in place, you've got cruise! :)
If you've got a decent u pull it by you and want cruise on your older Saturn, you can generally do it pretty cheap, and it's really nice in the end....
