go to techservices.audiovox.com and resister for free. Its not as badass as directechs but it will get you by. I would have just copy and pasted but it would have looked like crap on here, and I'm too lazy to edit it all up.Ever since directechs has changed the site, its now integrated into my works portal, so i haven't been able to access it from home

All,
I have 08 ford F250 Diesel 4 door with factory Power locks and Keyless entry.
I have 2 remaining issues I've yet to resolve.
I'm unclear about the power Door locks what style they are and how to hook the alarm wires into them.
The DEI Alarm Manual 5900 SST says
Light Blue -- (+) LOCK (-) UNLOCK OUTPUT
Green (-) LOCK(+) UNLOCK OUTPUT

My Schematic has two options
1- Standard Vehicle
1- Optional Factory wireless entry system (This is what I have)

Audiovox Says---

DEI says----

They both say similar but different things.
I also read the How to Tell what system I have. But was left more confused.
and dont want to experiment then burn up something.
Can some one tell me what system I have? and if I need to have relays etc..
Thanks to all in Advance.

green to blue/lt. green
lt. blue to yellow/purple
The motor wires don't get used unless you want 2-step unlocking (Hit unlock once drivers door unlocks, hit it again the remaining doors unlock).

All.
I have and 08 F250 Diesel Ford Superduty.
I installed an DEI Immobilizer Platform 04 Firmware PKFORD
I wired it in, and Programmed.
With the key near the Key switch my vehicle starts.
If I take the key away from the key switch NO GO
I get the SECURITY LIGHT in the DASH MSG.
I hear All the vehicle electronics start but no START.
I tried to reset and re-program the unit Many times. same results.
I tried reversing the RX/TX wires NO go. I made sure No ground was present at the Brown wire. still No Go. any suggestions?
Thanks in Advance
Sam

The brown wire needs to see a ground during the remote start process. This is what turns on the bypass. Hook it up to the ground while running wire of the remote start.

Great I will give that a try.

I would like to have the two step unlocking though.
What would be the wiring of that?

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?

did u program your bypass correctly?

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.
