Hello,
I have a CarVox King auto alarm system in my 1999 Dodge Caravan.
Last year I lost my remote and today finally found the backup remote.
The problem is, it is apparently not programmed to the alarm control unit. The directions call for the alarm system to be disabled in order to program the new remote unit.

Each time I reconnect the power to the alarm, it goes off so I cannot get it to the disarmed state.

I an asking what wire or technique I should use to disable the alarm.

I have attached a copy of the wiring diagram for the alarm and I think I need to connect the Yellow wire to positive, however when I test the wire with a VOM it appears to be a negative wire and I fear it will short if I try that.

Thank in advance for assistance. posted_image

5). Within 6 Secs, ....

6). Press Button "Lock" for 0.5 sec of New Remote
7). Press Button "Unlock" for 0.5 sec of New Remote
8). Horn Sounds for 5 times

Remote Start harness is not connected to the alarm.
Remote start was never installed with this alarm.

Remote may be out of sync Try pressing the unlock button repeatedly to see if it will sync up!

"Yellow (+) Ignition of Key Cylinder Input" should be hooked to the Side of the key that has positive when key is on. If you hooked up the starter killer relay it would be hooked up after key ignition output and before the relay.

The manual doesn't have a disarm without remote instructions?

To disarm the alarm "with yellow hooked up" Turn key on and with in 5 seconds press the valet button 5 times or more to disarm. Horn will sound twice and lights flash twice.

If the yellow wire is not hooked up you can't get into programming mode to program a new remote either!

The problem is, as soon as I connect power to the alarm box it goes off within a few seconds. I'm assuming the default state of the alarm is in triggered mode so that if you lose power and it's reconnected the alarm treats that as a theft attempt.

I need a way to tell the alarm it is not in triggered mode when I put power to it.

I tried hooking the yellow wire to positive and negative but the alarm seems to ignore it

Just hooking up the yellow wire is not going to keep the alarm from triggering.
You have to turn the ignition on and press the valet button 5 times or more in 5 seconds or less from the time you turn the ignition on to disarm it!

Just hooking it to positve dose not allow for the timing to be followed to press the valet button in the 5 second window that is needed to disarm once the yellow wire sees input.

Hook up the battery let it self reset (time out) open door which will set it off get in turn on key press valet 5 or more times in 5 seconds.

No aftermarket alarm can be turned off Disarmed by just turning the key on. Some Code Alarms could be wired to achieve this but, this would not be a typical install.
