Typically:Unlock Doors with Remote,Door Key or Turn Ignition On will Dis Arm Factory Alarm.
Be sure the Battery is fully charged.Lock & close all doors & hood.Leave vehicle undisturbed for apprx 30 minutesAfter apprx 30 minutes, Unlock Door & start vehicle.
You can also DisArm / Disable the Factory Alarm by:Find the Dark GREEN / PURPLE wire located in the 55 Pin connector at the Driver Kick Panel / Door harness.Connect one end of a piece of wire to the Dark GREEN / PURPLE wire.Connect the other end of the piece of wire to Ground (chassis).This will DisArm Alarm until the wire is removed.
If you have both Factory & Aftermarket Alarm (sounds like it), then try this to reset:
Be sure battery is fully chargedDisconnect Positive Batery Cable.Open Driver Door & LEAVE open.Turn Ignition switch to On position & LEAVE OnReconnect Positive battery Cable.Horn & / or Aftermarket Siren may sound for a few seconds.Start vehicle
If you are refering to the disconnection of the Battery......NO, pulling fuse will not accomplish the same reset.
Please explain why you want to track down the wires for the Aftermarket Alarm..........Unless you are wanting to remove it.If you have a Brand Name, please post it also
