Here's an odd question I'm hoping someone will know


Doesn't anyone happen to know if the door jam switch for the dome light on a 3rd gen PU or 2nd gen 4Runner is just a ground interrupt, or actually has a 12+ intput and a 12+ output?





Reson being, I have an alarm wired into my 91 PU, and it has a 12v ignition input, so that you can make it go off when the key is turned if the alarm is armed. Well I want to hook that up so that it'll go off right when the door's opened up; you don't have to start the truck to steal $250 worth of stereo



Thanks fellas!

 

The wiring diagram I have for a 95 4Runner shows the switches as ground interupt. Wires come from something called the 'Integration Relay' through the switches to ground. The driver door has it's own wire and the other 3 are all on the same circuit.

 

hmmmm


cool thanks!

well dang; I wander if that wire for the alarm will trigged with a ground too? I guess it's easy to test, once the battery's back in the truck

 

Integration Relay is a small gray "brain box" type thing plugged into the back off the fuse block... controls some of the switching functions and delay timer for the ignition key light among other things.

 

If your "alarm" only has 12+ and ground then it is a voltage sensing alarm. What that does is when the dome light is triggered on by the door opening, the key is turned on, the headlights, etc. it "senses" the voltage drop and cycles the alarm.

NOt the best way to go at all, and even still most of these type of alarms usually have dedicated negative inputs for pin and door switches.

 

well see it does since voltage drop for a trigger, and turning the headlights on or turning the key DOES trigger it. The problem is that the dome like is an LED replacement cause it's SOOOOO much brighter than a filament festoon bulb... therefor opening the door doesn't create a significant enough drop in voltage to trigger the alarm

 

Have you got power win/locks? you might be able to use the red door light feed as a trigger if you kept those a filament bulb...

 

no, all manual

working with a base-model...

 

oh well the idea was good anyways...

 

lol, that it was sir
