Hi everyone. I'm trying to find out how to either disconnect or fix my alarm system. It's the factory alarm, I think it's called a Denso. It keeps going off by itself. I've tried disarming it but it comes on again a few minutes later. Anyone ever have this problem? I disconnected the actual horn part of it so I didn't have to hear it every ten minutes! But the lights still flash. If I end up having to disconnect it how would I do it? What else do I have to remove? Thanks for any help.

First remove fuse for alarm, if that doesn't help then disconnect alarm box which is located on the upper right side behind the glove box. Search faq for intermentant wiper problem, that section gives accurate location of alarm box and how to remove it.

The alarm goes off randomly:

Rodeo: It's the tailgate switch. Open the door, take off the 2 Phillips head screws that hold the pin switch on (the one that controls the light) and stick two or three washers behind the switch under each screw.

Also check the hood pin: It's by the ABS module over the pass side front fender well on the 1998+. The pin is covered by a rubber boot.
