Despite what I said earlier in the thread, I just installed a keyless entry/remote starter dealie in my 5-speed car...
The wire I chose to use for the parking lights was on the lighting switch itself. It's an 11-pin connector going up to the switch in the steering column. The wire I used was red on the receptacle (switch side) and black/red on the plug (harness side).
I hooked the remote starter up so it'd only work if the transmission was in neutral, and so it would shut the engine down if anyone were to try to put the car in gear. Here's how:
The remote starter has a hood pin input that prevents it from working if the hood is open, or cuts it off if the hood opens. You typically install a microswitch under the hood so that the hood pin wire gets grounded if the hood is opened.
You can also connect the neutral switch to this wire. Cut the neutral switch wire going to the ECU, and connect it to the cathodes of two diodes. One diode's anode goes to the ECU's neutral switch input, and the other diode's anode goes to the remote starter's hood pin input. You can leave the hood pin switch connected as well. The diodes keep the ECU and the remote starter from interfering with each other.
magicmike - Have you ever installed a trunk lid opening solenoid in a Subaru? How's it work?
stipro - You just need a pretty standard door lock actuator to stick in the driver's door. It'll have two wires on it, which you'll connect to a pair of relays or something in order to drive it in both directions, unless the alarm has the capability to drive it directly. The manual for your alarm should explain how to hook it up.
That actuator, if properly installed, should be able to push the driver's door lock switch far enough to activate all the others through the car's factory "power assisted door locks" system.
