I have a 2008 ford mustang GT I am installing a Clifford X-50 alarm and I seem to be having one last issue before getting this working fully. My relay will turn my supervision lights on during disarm and I can hear the relay click, but they will not turn off when I arm. If I understand relays, (not my specialty) the relay switches from 87a to 87 (or visa versa) when activated. How do I get it to go from 87 back to 87a. I believe this is my problem. Does it require some kind of other component to do this? Thanks for any help ------------- 08 Siver Mustang Modified

What wire in the vehicle did you use for the domelight wire?

The car is keeping the domelight on, not the alarm.

Correct except I have the polarity set to (+) I think because it seemed to work backwards. ------------- 08 Siver Mustang Modified

If I only hit new keyfob to arm, nothing goes out and lights will dim after about 25 seconds but shock sensor will only work on alarm. But factory alarm is not set. If I arm car keyfob first then new keyfob factory alarm all seems to work along with new alarm funtions. ------------- 08 Siver Mustang Modified

I coudn't find the install manual for that alarm....but it might be equipped with a domelight delay learning feature. When, you hit unlock on your alarms tx, it is triggering the cars factory domelight delay, as Jworm said.

sounds like u don't have the correct factory disarm... or your light is stayin on because the relay is staying activated..... u may have to program a feature on the system.... or u mite have yourself a bad output on the system...... what the other guy said about how to wire it up sounds rite though..... if u followed that u should be golden..... otherwise... get your dmm out and start probing wires..... it will tell u where the problem is... and why it's happening.......

I can't find any info on an X-50 anywhere....is that the full name of the system? How old is it or is it a newer system?

I looked all through the manual and found nothing about a domelight delay learning feature.

Ok...that helps out alot. Are you using the h1/9 BLACK/ white wire to drive the relay.

The H1/9 is the (-200) ma domelight supervision output ------------- 08 Siver Mustang Modified

Date Posted: March 17, 2008 at 10:14 PM
Yes it is being used from the alarm to drive the relay and is connected to pin 85

At least I believe that pin 85 drives the relay, I am not to good with this relay stuff.  ------------- 08 Siver Mustang Modified

Ok,so what did you mean by this? 08silvermustang wrote:

the domelight wire in the vehicle is a (-).....so changing the polarity to a (+) should of never turned on the domelight....in fact, if the domelight was on, and you hit unlock on your 50.5 you would of blown a fuse. -------------

The alarm has a factory alarm rearm and a factory disarm. Would the factory alarm rearm be the same control as the arm feature on the original key fob? I checked all my connections pretty well with a meter but things can come loose. As I was saying before If I arm with my original key fob first then with the clifford keyfob then the alarm works, and when I disarm after the same procedure the factory alarm is off. It might be possible that some wire has come loose or something. Could this possibly be the problem? ------------- 08 Siver Mustang Modified

I also got the direct wire printout for the wireing color codes and I will have to look again but I believe I remember seeing two Lt. blue/pink wires. The printout says use this wire for Factory Alarm Arm, Maybe I have the wrong one. It says it is located on pin 18, and maybe I made a mistake when counting those tinny little pin numbers and the one I found could also have been the dupicate color by some strange chance. ------------- 08 Siver Mustang Modified

Factory rearm will arm the factory alarm....this wire will go to lt blue/pink (-) arm wire in vehicle...disarm will go to the lt blue/black (-) disarm wire of the vehicle.

Can you arm the OEM alarm and turn the domelight OFF by turning the key to LOCK in the drivers door with the doors closed? If you cannot, then this is going to be a lot more difficult. I don't recall seeing a Ford that allows arming the OEM alarm without using the OEM remote, or by locking the door with the door open. They may have changed that recently. I have been out of the industry for 2 years now, so I am not too familiar with all the new cars.
To have the aftermarket unit not show the door as open you have to turn Door Sensor Bypass Chirp to OFF in programming. After the domelight turns off, the alarm will then start to monitor the door trigger.

Well that sucks. Whats the point of an aftermarket alarm if you have to carry two remotes to get all your features. As per your sugestions they are well apreciated. The 3rd sugestion when you say door trigger do you mean Lock Motor? The Direct wire printout says that the lock motor has a polarity of 5wi Does this help determine the pulse problem? That would be a nice fix and if I can't get a door signal the horn would sound setting of the shock sensor and signal me anyway. ------------- 08 Siver Mustang Modified

I was thinking that also Jworm....will that still show a door open on the lcd, when he arms the system..I don't use DEI, so not sure. Heres another link I found. It won't turn off the domelight, but it will give you 2 independent door triggers, that won't have a delay. I've never used it, so i'm not sure if it works. https://www.canadiancaraudio.com/online/install-related/21696-05-06-mustang-door-pins-question.html -------------

The direct wire printout says Lt. Blue/pink and Lt. Blue/black but this could be wrong. the two blue wires are lt. Blue but are slightly different shades of blue, one darker than the other but not as dark as some of the other blue wires in the loom, they look lighter. I found that odd when doing the hookup. ------------- 08 Siver Mustang Modified

I edited a previous post where I was talking about pulsing the doorpin while arming the alarm. I didn't realize that a "factory alarm rearm" wire is now listed on the latest generation Mustang.
When I said door trigger, I meant the true door trigger. I believe it goes to an open circuit when the door is open, and ground when the door is closed. DEI does not list it on their tech sheet. You would have to wire in a relay to break the connection when you arm the alarm.
Ford does not care about you arming the OEM alarm with an aftermarket unit when they design the car. The aftermarket alarm company has no way to replicate the RF signal that the OEM remote sends to the OEM alarm. That is the problem. If you can arm the alarm another way, it may be possible to get the aftermarket unit to do everything.

I have seen directwire list factory alarm rearm wires that don't arm the OEM alarm. Try arming the OEM alarm by turning the key in the door to lock. If it does not work, then you have to lock the door with the door open.

You say: I edited a previous post where I was talking about pulsing the doorpin while arming the alarm. I didn't realize that a "factory alarm rearm" wire is now listed on the latest generation Mustang.
Is the "factory alarm rearm" supposed to do the same thing as arming with the original ford key fob?
I might have just picked the wrong wire or somthing has come loose. ------------- 08 Siver Mustang Modified

For most cars, the wire goes to the key cylinder in the drivers door. When you turn the key to LOCK it sends a ground pulse to the OEM alarm or BCM telling it to arm the alarm. For over 15 years Ford never had a wire like that. The OEM alarm would arm if you locked the door with it open, or if you used the OEM remote.
To test if you have the right wire...
The wire will meter 12v (positive) at rest. When you turn the key to lock, it will go to 0v (ground).
If this wire does go to the key cylinder and does in fact arm the alarm it will probably turn the domelight off as well.

I went down to my garage to get my manual. I have an active anti-theft system, it covers doors, hood, trunk, motion inside vehicle, cange in vehicle inclanation. As has been said: 1:It says to arm the system press the remote key fob (duuuu)
2: lock all doors using the interior powerlock switch while the driver or passenger door is open and then becomes closed.
3: lock thev driver door with lock cylender but this will not arm all functions. ------------- 08 Siver Mustang Modified

I did a complete rewire on a 66 mustang not too long ago and it was pretty easy back then. There could possibly be a wire for rearming and I just have the wrong one. ------------- 08 Siver Mustang Modified

I have looked everywhere on the forum to find this information. I have a Clifford 50.5x on a 08 mustang with an active alarm system as well as the passive. Why doesn’t my active alarm arm or disarm using relays to pulse the lt. blue/pink wire to arm or my lt. blue/black wire to disarm work for my active alarm. The most updated direct wire hookup is for a 07 mustang from what I understand they are the same. ------------- 08 Siver Mustang Modified
