alarm/remote start, 06 subaru legacy gt

I have been unable to find a wiring diagram which reflects my color codes and locations to make connections for remote start and key bypass modules. Have found several schematics but only some wiring locations and color codes agree with my vehicle. As a retired EE, I am about to give up on being able to make this install. Any help will be appreciated. I have the factory service manual with wiring and this doesn't even agree with my vehicle in some connections, particularly those to and from the ECM connectors. BTW, I am attempting to install a C3-601 (Autopage) remote start with a DEI 556UW bypass module.

I did a 09 which should be the same:

Dash Comes apart pretty easy, But the steering Column Shroud needs some care. The bottom half comes off easy enough by unscrewing the visible screws, but the top half is screwed in also. There are 3 screws holding the top half in and are only accessible after you remove the bottom shroud. You shouldn't need to remove it, but if you do, make sure you find the 3 screws before trying to pull it up and off.

Ignition wires:
12volts - white
starter - WHITE/ black
ignition1 - green
ignition 2 - blue
accessory - yellow

Also at the steering column:
Positive Parking Lights - Orange in a 4 pin connector near the steering wheel on the bottom. It only had 3 wires in it, the other 2 were white.

You'll want to use positive parking lights as the negative parking lights do not work with the ignition off. So when you use your keyless entry, the parking lights won't flash.

You also don't need the keysense wire that is listed on some wiring charts.

At the brake switch is the brake wire - BROWN / white

at the BCM all in the same plug is:
door lock - BROWN / white(-) test by pressing the drivers door panel door lock switch

door unlock -BROWN / black (-) test by pressing the drivers door panel door lock switch

disarm - Yellow/red (-) test by turning the key in the door lock cylinder on the outside of the drivers door.

Trunk release - WHITE/ black (you need to use a relay and cut the wire and "5-wire" it) test by pressing the trunk release button on the keyless remote.

When prewiring the remote start, I would use 2 diodes to split your trunk release output. One output would goto the disarm wire and then the other would goto the relay. This way when you are popping the trunk, the alarm won't go off.

Hi and thanks for the quick comments.
I obtained access to under the panel and steering column without any problems. I don't plan to parallel the door functions so my install will be less involved. I do need to locate and connect to the neutral switch was supposed to be the ECM WHITE/ green plug on pin # 31, a purple wire which seems not to be connected to the switch. You info on the parking lights was new to me and most helpful. The key sense wire is another which I did not find where it was supposed to be and possibly it is a BLACK/ white wire in the ign harness.
I will take a look at the 2009 connection assist wiring info available and see if this can be of help .
Thanks again,
Danny

Here is a photo of the BIU with the lock wires marked  :

Soldering is fun!

Is this an automatic or standard transmission vehicle?

Hi; Thanks for the question. It has a factory equipped automatic and it is a Legacy GT with standard 4 cyl turbo engine. It is equipped with the factory installed remote door lock and alarm system. I do not plan to incorporate these existing functions into my install of the remote start which will have it's own separate remote fob. The vin # 4S3BL676864200641.

If its an automatic then all you need to do with the neutral safety switch is either ground it or ground it through a toggle switch if you wish to have a means to prevent the remote starter from functioning (for working on the car, etc)

Thanks, this is also helpful but still indicates the shortage of info for this particular car and installation.
I am still missing valid info on the plug and pin # or wire color and location to obtain the tach signal needed for the RS-601 starter module. Might you know this one too?
Thanks again.
Daniel

I appreciate your posted reply with nice photo. However you show function connections which I won't be using due to my retaining these functions on my factory installed remote.
Refer to my other posts regarding details on where I stand now which is primarily the location of where to connect to obtain the tach signal. Any help on this one?
Thanks, Daniel

Here is the info from DEI.
Tachometer    pink to RED / White  (AC)      @ ECM, 35 pin plug, pin 22 or cluster
The ECM is behind the glove box.
On the 4 cylinder turbo models, the tach wire is in the 34 pin plug, pin 23.
Can also go to a fuel injector under the hood and use the wire that is NOT blue/black (4 cyl),
red (4 cyl turbo), or yellow/blue (6 cyl).

I usually just go to a F.I., determine the non-common color and tap into it at
the connector pictured below. ( 2010 Forester non-turbo )

I actually went to the cluster to get the tach wire, I believe it was the only RED / white. The GREEN/ black speed sensor wire was right next to the RED / white tach wire. The cluster has 2 screws under a little trim piece that is below the cluster, but above the upper steering wheel shroud. I had taken off the upper shroud earlier. Not sure if it was needed or not to remove the cluster.
i also had not integrated any of the keyless functions as the 09 legacy had the keyless built into the key. I used a 1 button remote starter to start only. If you power up the keysense wire the factory keyless function will not work while the car is running... so, like I said before, that wire is not needed...But you do need to hook up the yellow/red disarm wire, this way the factory alarm doesn't go off when remote starting.

Thanks; This is very helpful and another piece of the puzzle. I will check out this and the other suggested connections next week if and when the weather permits a my garage lacks space to work on the car.

Hi Kreg357; Thanks for the info and the photo. This is helpful and I probably will make the Tach connection under the hood as you suggest. I am attaching an actual photo of under my dash and you will note that my ECM is located on the steering column and not behind the glovebox. My 2006 I suspect is one made during the mid year changes they made that year and why the factory manual schematics are not totally accurate. I think this may be why I have had such a difficult time sorting out exactly where to make the necessary connections for the remote start and key bypass modules.

Thats picture is actually the BIU. It controls "body" functions such as door locks, factory alarm, possibly lights,brakes, horn, Dome light....

The ECM is located Either behind or below the glove box. When I say below the glove box, I think it might be underneath the top half of the carpet on the floor. You might not even need to remove the glove box to see it... The ECM is for engine controls. The fuel injector wires will leave the ECM, go through the firewall and to the fuel injector itself, but it originates from the ECM. The ignition Coil wires will also originate at the ECM and go through the firewall. You can use the tach wire listed as RED / white at the 35pin plug(c), Pin 22 of the ECM or if you have the service manual, you can also locate a fuel injector wire or ignition coil wire. This is all if you want to keep the connections within the car and not under the hood. Sometimes its just easy enough to go through the firewall and connect directly to the uncommon wire at the fuel injector or ignition coil.

oh, and in that picture to the left is a silver box with 2 plugs(1 gray, 1 white) I "believe" that is your TCM. TCM is your transmission control module. Again, if you have the factory service manual, you might be able to find a TACH there also...

Thanks Flobee4; I have been looking at the wrong module and n wonder nothing made sense.
Not to make excuses but the Subaru factory manual on CD/DVD has much to be desired for clarity and location of modules/wires. It does show all the plugs and harness but.......
below is the ECM located in the upper floor mat area in the passenger side. I will now verify the wires needed and see if they agree with all the tips this forum has provided for me.
Thanks also for pointing out the TCM's location.
