It says you can catch that wire at either the keyless control module, the instrument cluster, ground side of trunk light, or the trunk compartment light switch. And of course any where else the wire runs between those points.
I just checked a 2005 wiring diagram. It's brown on that one. Looks like 2009 they changed the color on you!
Isn't the keyless control module in/by the kick panel? It's hard to tell which way the wire is running from a wiring diagram. It just shows the connections to which circuit.
2010 wiring is the same color. Brown/White.
This install got me thinking. It seems like the sensor is getting battery power, ignition power, ground. It has one output, which sends a ground which is connected to the trunk light circuit. That makes the factory alarm go off.
I want to install a glass breakage and tilt sensor. I don't really care for shock sensors, they seem to false the most. I'm going to start doing some research as to what aftermarket alarm sensors will work.
Thanks again buddy, you really saved my *** with this one.
I was thinking of aftermarket alarms, but honestly for 40 bucks compared to 400 installed for a solid system this can't be beat. All alarms can be overcome, but at least this gives that one small layer of added protection.
Hmm.....I never heard of asianwolf brand. Most people buy DEI brand sensors which is Viper, Python, Clifford, etc. It seems like it would work as long as you diode isolate each sensor that your connecting on that trunk wire.
Yea i think so too. Except would you need to isolate each line though? Since the shock sensor has you install the diode in series between the two ends of the trunk light trigger, couldn't you just tap in another sensor between the diode and keyless module? I assume the circuit has a diode built in if it is made for a negative feedback trigger.
On aftermarket alarm installs, they always diode isolate each additional sensor on the "alarm sensor" input wire. It is to prevent false alarms. So I would too also diode isolate any additional sensors you install onto the factory trunk wire.
I can't find a tilt sensor that would work. A tilt sensor needs an additional input wire. It is hooked up to a "ground when armed" output on an aftermarket alarm. The wire is used so the sensor can memorize the tilt of the vehicle when you first arm your alarm. Any deviation of tilt, and the sensor will output the ground to activate your alarm. Unfortunately, I cannot find a wire/output on the factory keyless control module that has a similar function to provide a ground only when the system is in locked state.
Glass breakage sensor should be ok though, they are usually just three wires, power, ground, and alarming output. I really want a tilt sensor to protect the wheels in case someone jacks up the car to steal them. I know it's not foolproof, but Just a little bit extra security.
Gotcha, yea I realized that after I posted. I thought about tilt as well, but my shock sensor picks up the vibrations from the car being jacked (tested it ). That asianwolf glass sensor gets some good reviews, I also looked at the DEI glass sensor, that one can be had for roughly 15 bucks and is also can be used as a 3 wire design (4 wire if you want the chirp function), and the instructions detail how to install on non DEI systems.
