Hey,

My '04 has an aftermarket alarm installed and I wan't to remove it. I have never had fob's for it and it really drains the battery.

I have found the motion sensor and have removed it with no issues but I can't even find the Brain.

Can it just be unplugged or de-energized or is it more involved than that?

Thanks,

John

All modules, wiring and fuses related to the aftermarket alarm should go. O.E. circuits that were spliced or opened will need to be repaired. It usually takes between 1 and 3 hours. The added on stuff is usually easily recognizable and poorly installed.

Thanks Marty,

I would most certainly remove and repair all of it if I could just find the main brain. I bet it is in the center with the radio and climate control.

I guess I can follow either the valet button or horn back to get an idea.

Have you searched around in the engine compartment?

If you know the brand and/or model, Google it and download the installation instructions so you can work backwards.

Whatever you do, don't cut the blue wire

or is it the green wire

I have and I have also looked in each fender well, under the knee bolster and behind the sides of the foot wells, that is where the crossovers are located.

It will probably be easier to take it to a good audio shop and call it a day.....

In my experience as an MECP certified installer the aftermarket alarm was blamed for draining the battery way more often than was actually the case. The alarm would be removed and the problem would continue. If you don't have the keypad for the alarm and you're not arming it, it should draw even less current. If you can find the brain, getting a new keypad and having it programmed may be an option. You could even program it yourself. It's usually not very difficult and the replacement keypads come with programming instructions.

On the other hand if you find the brain. Unplugging it should solve any problems. As far as the car is concerned its like the alarm isn't there anymore.

Best answer yet thanks and you are correct these cars load the battery by themselves.
