99 GT Cruise install

[nancygrl]

I've got one of those 99 GT's that came with Automatic, power windows etc and no cruise control. I've checked and I know it's prewired for cruise. I've got a new Steering wheel with the cruise switches and the servo controller w/cable. Is there anything else that I need (ie...brake pedal switches, PCM programming etc) to get cruise control operational in my GT?????

Any help will be greatly appreciated.

sorry for the non info reply. but i thought it would be alright to put a toggle switch on my odometer to turn off the mileage? now when i turn it off my speedometer an cruise control don't work?
just thought i'd put that out there so you didn't feel left out with no cruisecontrol.

wiring diagrams 31 cruise control

Interesting question. I am 95% certain that PCM programming is not required. The PCM has all of the inputs it needs. However, a review of the wiring diagrams indicates there are jumpers to remove. There are also optional switches to add (1 for manual clutch, 1 additional brake). These switches may or may not be on your car.

Fuses such as F2.17(15a), F2.33(15a) and F2.35(15a) in the Central Junction Box (CJB) may be missing as well.

I just don't know.

IMO the wiring diagrams may help in trying to determine what is there and what is not. The diagrams I have access to are for a 2002 but the differences should't matter.

Note, the WEB interface will not let me upload all of the diagrams. PM your email address and I will send.

there was an option for no cruise control in 99?

why not just plug them in and see if it works?

 

[nancygrl]

Thanks wmburns....your wiring diagrams help alot.....Thanks a bunch

I did...doesn't work....From the wiring diagrams wmburns sent...looks like I need a brake pressure switch. Which is not there...So off to my local Ford dealer

I suspect there is something else missed. Check fuse F2.17(15a) in the Central Junction Box (CJB). Note the dashed lines around it. That means an option.

There may be other fuses not present such as F2.33(15a) and F2.35(15a) in the CJB.

If the switches are not present, it is a sure bet that the fuses are not as well.

Are you aware for the 1999+'s, the mileage is stored in the PCM? Turn off the cluster. Pull the fuse to the cluster. Change the cluster. In the end, the mileage counter is still ticking away in the PCM.

The only thing I can think of is to disable the VSS. However, if you were to do that, there are other controls based upon car speed that will not work (speedo, hi/low fan, engine load, PCM self tuning). The bigest problem is with the automatic transmission. As a electronicly controlled transmission, the car's speed is vital to the selection of the correct gear.

Your idea may work for the 1998 and prior as the odometer is electro/mechanical.

I have all those fuses as I suspect they are also used by other things. The only fuse I don't have is #6. would you happen to know what that one is for?

 

[wmburns]

Suspect that you do not have the correct fuse numbering. Fuse #6 is the starter relay (a required fuse).

Before I go through all of the diagrams looking for fuse F2.6, let's make sure it really is the one you are interested in.

Look at the fuse panel diagrams and you will see that at least one of the fuses is for the cruise control servo only.

Yes...i have #6...it's the one below it that's not there...it was late, and I just looked to quickly...my bad.

And, also, what legitimate reason is there for disabling the odometer?

 

[wmburns]

Reviewed the diagrams and now think that all fuses needed are in place. Fuse F2.17 is also used for the Brake shift interlock.


F2.17 Speed control servo (9C735), Brake shift interlock
F2.33 Brake pressure switch (2B264), Brake pedal position switch (13480)
F2.35 Powertrain Control Module (PCM) (12A650), ABS control module (2C219), Speed control servo (9C735), Brake shift interlock

Then why when you change out your instrument cluster you have to swap out your odometer?? to keep the milage??
An when i turn it back on the speedo. it doesn't add all the uncounted miles
Yes your true bout havin an automatic this won't work to many sensors run off the speed sensor.

AS for "Patman0911" adds value for less miles not that i'm really goin to be sellin my stang anytime soon?

 

[patman0911]

Yeah, that's kind of illegal and dishonest.

mileage fraud ftw!

lol totally off topic, but my buddy put an ebay f150 cluster in his lease 08 f150 that was a few thousand miles away from the limit. Now its about 10k over the limit. Ill never buy a leased car.

This may be a Pandora’s box of curiosity but what year car do you have? Where did you install the switch (which wires)? Does your speedometer work while the "switch" is active?

Isn't the PATS module the reason for the swap when replacing the cluster?

Mileage is stored in the pcm. as in other modules.. If somebody really wanted to look they can find the true miles and then your car would have to be sold as true mileage unknown. If somebody does check you could be in trouble.

Either way do not discuss it on this forum.

Yeah, that's kind of illegal and dishonest.

It's more than kind of illegal... it's illegal and he could get a large fine and even go to jail for it.

You could get sued for up to 3 times the damages including repairs related to the extra mileage..

So making a few extra bucks on a car could end up costing you tens of thousands of dollars. Plus the judge will tack on all the legal fees by the time you are done you could end up owing hundreds of thousands.

I have seen it happen to people mostly car dealers but a few individuals to..

No the odometer is part of the cluster..

Either way I rather you guys post 1000 street racing threads than 1 thread talking about how to commit fraud on whoever bought your car someday.

So we are done with discussions about rolling back odometers and disabling it.

I feel bad about being a party to a thread hi-jacking. I am so sorry.

Is there anyway to "delete" the unrelated posts?

Yeah I can delete them but I don't think we have to.. I think we can all agree that the forum should not be a place to teach people how to commit fraud
