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. Danny

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

Is this an automatic or standard transmission vehicle?Kenny

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)Kenny

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 )
