You will need a PATS bypass module and an extra key to introduce the proper resistance to the PATS computer.

  • The RKE is a Remote Keyless Entry
  • The factory disarm is ( - ) input signal

The PATS bypas system is easy ... take a relay ( 30/40 amp ) and hook it up like this:

  • 86 - Primary ignition ( BLUE/GREEN )
  • 85 - Ground out when running on remote starter
  • 87 - Key cylinder( wrap a 22 gauge wire around the key cylider column about 8 - 10 times and connect to pin 87 . This wire must be 20 - 24 gauge otherwise it will not introduce the signal into the PATS properly and you will get hit and miss starts.
  • 30 - Spare key with resistor in the black molded top part. You must wrap the the same wire that goesinto pin 87 around this key about 8 - 10 times as well and connect to pin 30.

I hope this is easy to follow and if not let me know and I will put up a picture of this circuit for you later.

Four ways to do it, from best to worst:

1.  Go to any Directed Electronics (DEI) dealer and pick up DEI's 555F.  It will bypass PATS during remote start, and you don't have to give up any of your keys.  It comes with instructions.  When programming the 555F to your car, you need TWO working Ford keys.

2.  Buy any of the universal bypass modules out there.  DEI 555U, Audiovox AS-TCBM, et cetera.  You will need to permanently install one of your Ford keys into the universal module, and those keys usually aren't cheap.

3.  You can make your own hand-made 555U with a relay and some scrap wire, but it can be hard for a novice installer to get this to work properly.

4.  Pry the little plastic plug out of your key head; the PATS capsule will fall out.  Glue the capsule to the ignition cylinder.  (You'll have to experiment to find a spot that will work.)  You'll also have to remove the capsules from all your spare keys, since the car won't start if it sees two capsules at once.  This method is cheap and easy, but your car is unprotected against theft.  And if that capsule comes unglued, the car won't start, not even with the key.

Sorry, you can NOT post a reply.
