as mentioned in https://www.the12volt.com/installbay/forum_posts.asp?tid=48267&KW=subaru+Neutral+
for the 2005 subaru wrx sti the neutral safety switch is a great idea, however it does NOT rest at positive 12 volts when in neutral (as mentioned in above link) but instead is negitive (Ground) this presents a problem when connecting a remote start and interfacing the neutral safety switch wire to the hood pin. you cant, otherwise it will see the hood open when in neutral, and we dont want that. Instead, many alarms such as the audiovox, code alarm, and others have a remote start enable/disable switch. like a master over ride switch. you can connect your neutral safety switch wire on this switch (not the negitive lead side) which will eliminate the need for this switch. You can even install it in such a way that you can retain the switch if need be, but not necessary.
hope this helps, enjoy

The 05 Subaru is easy but the 04 or older is more difficult because when its in gear is negative and when its in neutral is nothing (not a true 12 volts. wont click relays). Also you canˇ¦t hook it up to the hood pin because when the car is in gear your alarm will give you a false trigger.

Does anyone know how install a remote start with the neutral safety switch successful on a 04 or older Subaru WRX with no flaws?

well, a quick and easy way may be to put in a relay. wire it up so that when in gear the ground that is present will trigger with say the ignition (use the ignition so that the relay is not energized most of the time) and the brake

Basicly like this:

86 and 30 to an accessory or third ignition on the remote start

85 to the neutral switch that is ground when IN gear

87 to your brake input/shutdown wire of the remote start (you may want to isolate using a diode as well)

this will basically tell the remote start that your stepping on the brake (assuming you have a + trigger brake wire) and thus wont let the remote start start. This is only useful if your brake wire is positive like the ignition, and there is a delay when starting from the remote start. IF the start function is instant when turning on the ignition then you cant do this.

Now there is probably other ways, but this is what i could come up with so fast. hope this helps

Here's a great idea...GET A REMOTE STARTER DESIGNED FOR MANUAL TRANSMISSIONS. They require a few extra steps but they are safe.

welp, the extra steps are cumbersome and though it may "work" personally i think it is far too much of a paing over using a .50 relay in this case. In addition IF you dont perform the steps when exiting the vehicle each and every time then the remote start wont function. and thats even if it is in neutral. so for the tweakers and modders in us, the relay idea is a more effective and usefull way especially if you already have the remote start unit.

That might work but when your driving you'll hear the relay clicking.

wow, you really needed 4 posts to say that? hehehe

anyways, actually you wouldnt hear the relay clicking while your driving since it would only be activated by the third ignition output wire, which you could diode isolate everything. this means that the remote start would only function when your NOT driving and when you press the brake it would deactivate the remote start and require the vehicle and its ignition system to run.

i would probably suggest at this time since it seems that your not to familiar with this stuff to have a pro do it for you, they can also probably suggest a remote start unit as well.
