How can I remove this without disabling the whole vehicle? It's an "aftermarket alarm" and I don't want it.
Just disconnect all the butt connectors? The alarm must be disabled 'cause it has never gone off.

Just my 2 cents on this. Contact the manufacturer and find out some more info on this. Why, because some alarms disable the ECM as well as make noise. When you tamper with them, then you cannot start the engine. So, I recommend a little homework before you mess with it

I have a remote start on my 2000 WJ that was installed by the PO and all I did was remove the 2 10amp fuses that power it. I looked at the box with all the wires disappearing into the nether regions and said "F that!" and left it alone.
