Ok guys I am going nuts here trying to figure this out:



Is that wire not brown(( the one lifted on the right))???

If that is brown, I went ahead and snipped it, and wired up the sensor and it still fails to trip the alarm.

That wire is supposed to be the trunk light coming off of the keyless module. How can I actually verify that?

HELP

Looking at a factory wiring diagram, it says you want a brown with white stripe. It shows it going to the trunk light switch.

oh .... well wtf did i cut then ???


i dont see a brown with white stripe, I see a brown and what looks to be a brown with black stripe (as seen in the pic near the bottom)

I am going by the instructions :

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!

well isn't that cute ... any idea what wire i ended up cutting?

edit: also, you have access to the wiring for a 2010??

Also I was just looking at the keyless control module .... there are 3 harnesses ... by any chance does your document say which of the 3 harnesses that wire would be in?

Err this is redonculous, i found it, looks like its one of the top right pins in the middle harness ...

brown with a white stripe ... comes right out of the harness to the wire bundle... wirebundle goes back against the fire wall, and around to the kick panel ...

Problem is that between the Keyless module and the kickpanel i freaking lose the wire ?!?!

I would prefer to tap it down at the kick panel near the other wires...

jrx13

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.

Got it installed and working:https://www.rx8club.com/series-ii-diy-161/diy-alarm-shock-sensor-upgrade-install-sii-215064/#post3947352

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.

jrx13

No I mean adding aftermarket alarm sensors to the factory wiring just like the shock sensor upgrade you just did. All I would need in addition are diodes just like the one provided.

Aha I gotcha, that would def be interesting. Lol I wonder how you would test a glass break sensor

jrx13

You tap a key against the window and adjust the sensitivity until your happy with how hard the tap is. That's how they do the microphone ones.

They have others that sense the difference in air pressure. You just install one sensor like under the hood and one in the cabin.

Here is something I found that is quite popular ... http://www.asianwolf.com/glass-sensor.html

Seems easy enough to install, and it uses a negative trigger which is nice since the trunk light is a negative trigger as well.

jrx13

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.

jrx13

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.
