remote start on 2002 mustang v6

I'm installing a cool start rs999 by Crimestopper, I ran into a problem with the Factory alarm disarm wire, the wireing diagram says that it's a DarkGREEN/ purple wire @ GEM 20 pin plug, pin 16. I looked out it over and over and that wire is not there ! the only way the car will remote start is if the key is in the ignition, any help???

The factory disarm wire, and the reason you're car isn't remote starting are two completely different issues. I really doubt that car even has a factory alarm. Are you using a bypass to get past the PATS system?

You've got two separate systems mixed up, factory alarm, and factory immobilizer.

Factory alarm: This is the system that sounds the horn and flashes the lights if someone breaks into the car to steal your stuff. However, it has no way of preventing people from starting/stealing the actual car.

Factory immobilizer, or "chip key" or "transponder" or various other names: This is the special security chip that's inside the large head of your key. It has nothing to do with the factory alarm, has no way of sounding the horn if someone breaks in to steal your stuff.......but, if the car doesn't "see" the chip when the ignition turns on, the engine won't start.

1. Did you first test the car for a factory alarm? I'm not even so sure the GT had a factory alarm......I would be doubtful that the V6 model would have it.

2. What are you doing to interface with the car's immobilizer during remote start? The remote start won't work unless the car thinks there's a valid key present.

3. How many keys do you have for this car?

There are various bypass modules available from various manufacturers, but they pretty much all need two valid keys to program.

ADS (idatalink.com) has recently been able to get their bypass module to program to the car with only one key.......but, you need not only their product, but their "weblink" cable which would probably cost almost as much as just getting another key made.

So, here are your options:

1. Get a second key made at a locksmith or the Ford dealer, and then buy a no-key-required bypass module and install it.

ADS (idatalink.com) Fortin (ifar.ca) and Trilogix (bypasskit.com) all offer modules for your car.

2. As in #1, you're already going to the locksmith. Most of the money isn't for the keys, it's for the labor and their expensive programming tool.

It might be cheaper just to get a third key made at the locksmith, install that in a universal key-in-the-box style bypass module. Might cost you less this way, than buying a no-key-required module.

3. If you don't care about reduced security, there is another way.

Go to the hardware store, get some non-chip copies made of your existing key....make as many as you need.

Put your existing chip key in a universal key-in-the-box bypass module, install the module.

But, wire the module so it comes on EVERY time the car's ignition is turned on, not just with the remote start.

This means your car is easier to steal, and you've lost the anti-theft feature of the immobilizer key.......but it is the least expensive way.

I did the same thing on my girlfriend's Taurus, but I was also installing an alarm with starter kill, so that offers a little extra protection.

thanks I tring to do it the cheapest way, Got laid off last week so money is a little tighter !  I'll have to look for a PATS bypass module thats not too much $$$,  thanks for all the help, I'll let you know how it turns out..

found a 555P Ford PATS Transponder Kit, doesn't need an extra key, you think that will work ??

As stated in my posts above, like all other bypass modules, it'll work once you have two good keys for the car.

if you wanna go the easy route you can get your key cloned at your local locksmith usually costs about 60 bucks...and use a 556uw...very easy unit to use and  you can find them dirt cheap online..

SAW 'EM OFF!

I've never installed one of those. Looks unnecessarily complicated, compared to some of the other modules out there, but it should work.

To access those immobilizer wires, probably the easist way will be to get them right at the car's immobilizer module itself, behind the ignition keyhole.

Look under the steering column shroud, and you'll see a few large holes there with screws inside, as well as one smaller hole.

Turn ignition to Run, insert thin tool into that narrow hole, push.....and then you can pull the entire ignition switch straight out of its hole.

Then, undo the screws, take the black plastic cover off the steering column, and you can see everything.

P.S. You did already get a second key made for your car, correct?
