2002 jaguar x type alarm

hey i have a customer that has an 02 jaguar x type. he wants an older python 323.

i have found 2 different wiring diagrams posted here, and was wondering if someone could clarify what is needed and what is not. the first examples are from the vehicle database, the others are posted from velocity motors, a member. i dont know which one i should follow...

for instance, vehicle db says the lock wire in this car is green and orange. orange is lock detection...diode isolate. velocity motors says just green. no diode needed. my question for this is do i or do i not need a diode?

the other thing is vehicle db says for the door trigger, use dome light supervision wire. the door trigger wire must be relay isolated to avoid false alarms. how do i wire a relay to do this? velocity motors says door trigger is blk/pnk. no relay isolation needed. can i just tag BLACK/ pink?

those are my 2 issues i hope i wont have to come across...thanks for your knowledge in advance!

Jeff is essentially correct, relay not needed for domelight.
This vehicle is essentially UK Ford Mondeo under the skin (Fusion) and I wrote the install guide for then Clifford, essentially the same with different colours. Forget door detection, vehicle is too old to worry about it.

Ok so pretty straightforward then...thank you for clarifying for me!

Hey update! The alarm was very easy as in finding wire colors, the Custy called me thus morning and said 15 mins after arming the unit last night and this morning, the alarm went off out of nowhere. I believe it may be the door trigger wire. He hasn't gotten back to ne as in how many times the led flashes upon unlocking the car after this happens, and it goes off only 1 time after arming about 15 mins later. So I can be prepared, and for future knowledge, can anyone tell me how to wire a relay to relay isolate a domelight wire? Thank you

Also if it helps, I tagged the lock detection wire (orange) as my lock wire, the green lock wire in the gecm wouldn't work as lock, but the orange worked fine. Not sure if this is related but that's what I did

Go to downloads, connect to all the door triggers as DEI 10776 diagram, don't do domelight supervision not needed.
It's the BCM sending a timer pulse after a sleep period.

The page isn't found or available...but if that tech doc is for the need of a diode I can do that no problem

Should be in the Downloads/Manuals section, DEI Tech Tips, if not go to Audiovox/code Tech or Bulldog.
2 X 1N4004 diode for each door hood and trunk trigger.

I found it thank you. I will see the car tomorrow ill let you know how it turns out

Hey bad news...it went off 30 mins later again. I wired the diodes (2 1n4004 1 amp diodes) just as in the tech doc...with the stripe from the alarm facing the bcm, and the bcm side of the wire with the second diode with the stripe facing the alarm. the trunk and door triggers stopped working all together. I would lock the car with the door open...no 2 chirp error warning. So then I used 1 diode with the stripe facing the bcm. The alarm chirped 2 times when I armed the car with the door open as it should. It did the same with the trunk. I thought it worked, but 30 minutes later, it goes off again. I have the correct wire colors, tested with a meter. I haven't really done cars with the need to diode isolate much and when I did, it worked fine. I'm very much stumped any help would be appreciated

OK did you also diode hood and trunk?
If not that's your answer.

Plan B Dome supervision and turn off door error, BLACK/ pink GECM, gray plug, pin 3.

Your circuit per door should look like this:-

Yes I did trunk also, his unit didn't come with a hood pin. I did use the BLACK/ pink domelight supv wire and the diodes look exactly how the diagram is. Which is why I'm stumped. With door trigger error turned off, wouldn't it still go off after the gecm "goes to sleep?"

When it goes to sleep then wakes up the earlier Ford GEM module sent a pulse at roughly 30-40 minute intervals. The double diode ideas is to block that pulse'
If you use the BLACK/ pink* you shouldn't need the diodes except for the trunk wire which only requires the one diode between where you joined to it and the BCM.
*Using the dome supervisor wire means you don't have to connect individual door pins.

When I used the double diodes, I didn't get any error signals (2chirps) with the door and / or the trunk open when I press arm (to test the unit) I used 1 diode for both just to see and it have me the error chirps, but it went off when it went to sleep

Disconnect from the door pins. Use only domelight supervision.

From the vehicle database it says blk/pnk @gecm gry plug pin 3 as door trigger..then the other which velocity motors wrote for user Patel, its the same wire color, location and all, but instead of being labeled door trigger, it says done supervision. Maybe this is where I'm confused?

Yes forget door pins, just wire your door trigger to that wire.

This is what I did and I'm still getting the error...without diodes, with double diodes and with 1 diode

OK use only pink black and diode + to domelight, band towards the light.
That's a trick from later Fords where the GEM and fusebox were combined to become the CEM module.

I tried that that way and it failed again. I used a relay and its been working fine for 3 hours now, I'm arming/disarming and turning the ignition on to simulate driving every hour and no false alarms yet

Good, actually I forgot the relay trick! Only used it once because it was cheaper to go with the diodes!
The relay coil can't be overcome by the "spike" when the system self tests.
This was always a problem with Clifford and later DEI products, entry triggers were too sensitive.
The other trick was a "strapdown" resistor, 10k between the trigger wire and 12V+
You must leave the car standing and alarmed about 30 minutes before completing the test.

Oh wow. Well I thank you for your efforts Howie! Yes everything is good still, now 4 hours later.

I suppose I never had problems because the vehicle it was based on(the British Ford Mondeo = 500 later Fusion), was extremely common, I did loads of them between 2000 and 2007, thrashed out all the problems and wrote the how-to for Clifford by 02.
