My condolences to Terry's family and friends. I have known Terry for a number of years and he rebuilt my SVT transmission last year. Terry will be dearly missed. RIP

Still no luck with the getting the cruise control to work, including trying a third cruise control module. Something I did discover, the published wiring diagrams for the cruise control switches for all MK1 and 2 Contours, Mondeos and Cougars, is actually incorrect. As per the link to a Contour cruise control electrical diagram below, it (and other similar diagrams I found for Contours) shows a common (real colour Brown) wire to all switches and the horn switch. This is not true, as I sacrificed a set of cruise control switches, and discovered that the ON button has a common Yellow wire to the cruise control switches, and the brown wire is common to the OFF, SET, RESUME, COAST and Horn. There is a third wire, a black wire (12vdc) common to the ON button and horn switch. http://www.autolib.diakom.ru/CAR/Ford/1997/Contour/SYSTEM%20WIRING%20DIAGRAMS/14761.pdf I can't say how this changes what I need to check into next, but it does make sense that when the ON button is pressed, it sends 12vdc through a 272ohm resistor, creating a reduced voltage input through the yellow wire which eventually goes to terminal 5 on the cruise control module, which is noted as SWITCH(ES) INPUT. My assumption is that thiis would signal the module to be ready or power up the module. All other switch inputs would then do as per their function name. Where to go from here? I didn't check the VSS signal voltage, other than with ignition ON, primarily because all posted literature states that if the speedo works, then the VSS signal to the cruise control module should be fine. Mind you, there is a junction point somehwere under the dash or hood, where the VSS signal splits off between the speedo and cruise so you never know. If I ever get this problem fixed, I'm going to need a break from this car. As much as I still like my SVT, the cruise control and some other recent issues (ex. Fuse box socket loosening and 15A fuse not making proper contact causing HVAC fan and turn signals to lose power), are starting to wear me down. :(

I'm going to see about running a new wire from the cruise control module VSS input to the main harness connector by the strut tower. Thing is that the existing wire does show voltage with key on, no voltage with key off. I might be chasing another ghost.

Still no luck with the cruise control. Verified again, all voltages, switches and connections, all except VSS voltage at the cruise control module. It's a hall type sensor and apparently need an oscilliscope to check. In any case, the VSS signal shows voltage when key is on position (7.2VDC) (O VDC with ignition off) and the speedometer works which uses a parallel signal from the VSS. This is a total mystery.

Hi Terry The clock spring was replaced, though the horn worked before the replacement. Horn still works. When ON button is pressed on the left steering wheel switch, 12 volts is seen between pin 5 and 6 at the cruise control module connector. When all other buttons are individually pressed on the cruise control switches, various resistances are seen on the multimeter when checked between pin 5 and 6. Greg, i'm thinking of mounting the multimeter inside the car, run the leads to the cruise control module connector and check the VSS signal for voltage changes. This is so frustrating, but no where near as frustrating as having 3rd gear let go while the car was barely driven for 7 years. Thanks to Terry, once again, for coming to the rescue and rebuilding my transmission.

Hi Terry The cruise control on my 98 Contour SVT does not work. I have replaced everything possible (with new parts) including every switch, the cruise control module and a new VSS. I have the correct wiring diagram and I have electrically tested at the cruise control module wiring connector and have determined that I have all signals (resistances) and 12 volts (or 0 volts) required that should make the cruse control work. The only thing I can say I am not sure of is what voltage should I see from the VSS signal. From my multimeter, I saw 7.9volts at idle, not sure if that is correct or not, but assumption was that there was a voltage so that pinout should be fine. Is there something I am missing? Some oddities about this SVT is that it is one of only 2 known production SVTs with factory traction control. The computer code is SFG0, build date January 1998, and it's a E1 built right at the transition between E0 and E1 models, so it has some E0 and E1 built into it. Even though I don't use the cruise control much, it's just one of those things that I want to have working when I do go for some long cruises this summer. Hope you can help solve this problem. Thanks, Chris
