Car Alarms: 2000 Mustang GT PATS Help, ford service, purple wire

Question
Hi, first I want to say that this website is really helpful... well heres my problem.. i have a 2000 GT and the "Theft" system is preventing me from turning my car, i have tried locating the dark green and purple wire that you have talked about in previous cases but I cant seem to find them... I did see a plug with those cables but nothing happened when I grounded them, on the back i have the fuel pump shut off switch and a little more to the front is a metal box... i disconnected to see if at least the theft would turn off but it didnt... another thing I want to add is that in the front right fender theres a black box that starts making a noise like a fuel pump when I open the ignition...I've thought about buying the unit that sends the PATS signal to the computer but I dont want to waste my money if thats not the right part. Thanks for your help in advance.

Answer
Troublesome system, and not an uncommon issue
by a long shot.

Ok, unfortunately you are correct,
this vehicle does have the PATS key
based engine disabling system, and currently it
does not recognize the chip in your key.

The towing and Ford service fees are not just annoying,
they can also be truely expensive when having to have
to do it again and again...

But...
If you want to just remove this system
from the equation entirelly,
I suggest the IB04-XKO4 PKFORD bypass
kit to get around the issue.

This Bypass Module is designed to momentarilly
allow the engine to remote start by sending a proper
coded pulse to open the fuel rail passlock injector
cut off circuit.

The output from an alarm/remote starter
would then shut down the pulse, once it has detected
the engine has engaged, and preserve the integrity
of the PATS system.

That is it's designed purpose.

However, in your case, this input wire on
the XK04 module, instead of going to a
momentary ground pulse from an
alarm/remote starter, would go to a
constant chassis ground, through
the bypass module, grounding out the PATS.
The PATS would always be bypassed as long
as that wire is chassis grounded.

I can not speak about a damaged PATS system,
like if a thief has destroyed it, because I do not
get into this part of FORD'S security application.
But as a happy coincidence to installing
after market remote starters, this does work on bypassing
trnasponder in most all FORD vehicles we've run into,
including your year FORD vehicle as well.

Also, this is a self learning, resistor sensing
and adjusting module. Once the PATS wires have been tapped,
you would press the program button to learn,
and it does. The car should then allow start
with any hardware store key.

Hopefully, it will on yours as well.
