brown wire from bypass will go to GROUND WHEN RUNNING or STATUS OUTPUT (DEI). this wire switches to ground during remote start.

if you want driver door priority unlock, you will tag the driver door motor. your unit should have 2stage unlock. take the driver unlock connected to a relay that will open driver, then on double press passenger doors.

Thanks for the door lock info worked like a charm.

The Immobilizer still no go. I tried the brown wire suggestion. It made it worse.

When I ground the brown wire it wont event attempt to start.

Before grounding the ground wire. It would start if I had the key near the keylock unit.

If I take the key away I get the Security light in the dash. Its as if the immobilizer unit

is not compatible... Still stumped. I've tried several different tests. I've tried unwiring things like the hood pin switch (just to test the unit is actually working) and it is.

is it possible this unit is not compatible? the paper work says it is. but when I goto DEI's site its not listed.

what diagram for the PATS connector are you using? for that car it should be diagram (B) pin 1. ignition pin 2. ground pin 3. RX pin 4. TX check those wires and also make sure you have two different keys when programing.

Im positive Im using the correct diagram

If I had it wired wrong either 1: It wouldnt work at all.

2: the light on the unit would stay solid or flash rapidly.

In my case it does work just not when the key is not near the pats unit.

Also I did rewire the rx/tx wires just in case I was wrong. it resulted in SOLID light.

so I returned to previous wiring.

could I be wrong? Also I tried Resetting many times as well.

If it were mis-wired Would it still work if the key was in the vicinity of the pats unit?

here is a new way to ask my question.

If I installed all the above alarm system along with a Ford Bypass unit.

would it remote start if it were wired wrong?

My unit does remote start but only if the key is within proximity of the pats unit.

now I know this means either I have it wired wrong, Programed wrong, faulty component

or and incompatible component. I've tried everything the installation manual says to do

in case of fault. and with no success.

simply put. with the key near everything works fine , take the key away I get a PATS security error form the dash not the add-on unit.
