My Mustang Cobra has a Viper alarm system that won't set

My Mustang Cobra has a Viper alarm system on it and I can't get the alarm to set.The light thats mounted on the dash stays on but does not flash. It worked when I had it installed, but I think I hit something on the remote that caused this problem. The switch that shuts the system off is up under the dash so I know I did'nt hit that switch. My remote has a numder on the back of it CE0890 I'am guessing thats the model number.

Thanks
Patty

Under the dash, Your installer that worked on your Cobra should have put an valet button under the dash, It is a small round Black button, Ok with the driver door open,,put your key in the ignition and go to the on position, Locate the black button before you do this, once the ignition is on hold the black button down for 3 seconds hit it once more and then turn the ignition off, the light should start flashing again and the chirp for arm and disarm with work again, What you have going on is called Valet mode which is designed to put the alarm side of the system to sleep which can happen from accidentally bumping it.

Hope this was helpful.

Cobra 7925 installation manual, user or wiring diagram please?

Good Day to you too.

We aren't a group, and we don't have members. We have people asking Questions and Experts answering them.

This is the only manual that has wiring and is fairly typical of all Cobra Alarm installation. This is a different model but it does have contact details on the last page.

Should I intall a Viper 5701 remote start on a manual transmission Mustang?

Honestly, you would be taking a risk. You have to remember that if you do, you will always need to keep the car out of gear in order to start the vehicle. You will also need to install an extra relay in order to bypass the clutch switch. Very unsafe, but good luck.

Had this viper alarm installed on a mustang and the alarm seems to go off every 30 minute

If your alarm is going off every 30 minutes its because a zone is backfeeding after the cars computer shuts down. First you have to find out what is back feeding... I would first disconnect the door trigger wire from the alarm to the car. Test it and if this is the problem then you should go to the latch wires of the car doors and not the interior domelight. If the problem is still there than you should check to see if the trunk trigger is the problem. Most techs pick up the trunk trigger in the trunk at the light. if you find that this is the problem then just remove the trigger from the light and add a pinswitch in the trunk.

My viper 2 way pager remote will not arm or disarm the alarm. it still shows a trigger when the door is open though. how do i reset the alarm remote to the vehicle?

It could be set on car #2. Press function for 8 seconds and a light next to lock should come on. If the light next to unlock and lock (two lights) then it is set to #2 car (you can operate 2 cars with one remote). All you have to do is press function again to toggle between the two cars. You want to end up with only one light showing.
So, hold function for 8 seconds, then after a light shows, release and press function until you only see the one light.
