hmm, you still need to use a diode b/c the hood pin itself will send a ground signal back to your ECU.
test it by metering your tapped ECU connection with the Hood Pin grounded. it will show ground even if your gear shifter is in neutral! your ecu will think the vehicle is in gear though the gear shifter is in neutral. 1 amp diodes aren't expensive, 10 cents perhaps!? and it will protect your ECU from getting an improper ground from the hood pin. netZ Quote:

Hummm.... my car already thinks I'm pressing the clutch all the time so whats wrong with it thinking I'm in gear??
Nevertheless using a diode would be the proper thing to do when merging two circuits like this but I don't have a hood pin switch so I think I'm all set! Thanks for the info though. |

sounds like you got a real hokey remote start setup!
installing alarms isn't your day job? i would have said don't quit your day job.. but i think i've changed my mind...hahaha j/k... all kidding aside, for us normal people... 1) Installing a proper Hood Pin for a remote start system is a must, you don't want to be wrenching in your vehicle when someone 'accidentally' initiates your remote start feature 2) Use a temporary clutch bypass method when you remote start a manual tranny, don't just disable it! Though it doesn't really matter if your clutch is bypassed since it only unlocks the starter. Tricking your ECU's Neutral Safety by feeding it an improper ground signal isn't a good thing! 3) If you're planning on tapping the ECU's Neutral Wire to the Remote Start system with a Hood Pin... be sure to diode isolate it. You are basically allowing your ECU to be suceptible for invalid ground signal to the ECU! And your ECU can be fried if someone were to zap your vehicle with a stun gun... laugh but car alarms have been disabled by a stun gun! People have already fried their neutral position switch already ... obviously, the Remote Start can't tell for sure if your vehicle is in gear b/c there's no ground signal anymore! You should at least test your remote start every so often in gear to see if the Neutral Switch is functioning. 4) If your remote start device needs to see a ground signal first before it will remote start, you can use the parking brake switch as well. Though it's not fool proof but it won't remote start without the parking brake engaged. Also use a diode, just in case the remote start sends a ground signal through this wire as well. If needed an additional Toggle Switch to go inline between the parking brake switch and the remote start wire will allow you to disable the remote start feature for vehicle servicing etc... Proper installation is a must! netZ Quote:

netZ, I guess you're the kind of person who comes to a complete stop at a stop sign in the middle of the night when nobodys around... as for me I'm <singing along> LIVIN ON THE EDGE!!!
Just to let you know I am not advocating people follow my unsafe setup, but since you jokingly attacked my workmanship I thought I'd explain myself... I decided not to install a hood switch because I want to be able to start my engine with the hood open, for example between spraying degreaser and rinsing off my engine bay I like to start the engine without having to get in my car. Of course this isn't the safest setup but if I want to disable the remote start when working on the engine I just leave a door open. Keep in mind the "door open" disable only works on certain remote starters. I highly recommend a temporary clutch bypass for cars that are lent out to friends, and for absent minded owners. I am not absent minded and I don't lend my car out to people who don't know how to drive it. So as a convenience I like to be able to reach in and start the car without having to push the clutch, for one reason or another I actually do this a lot more than I thought I would. For people that have a dumb girlfriend or sibling that drives their car, I certainly would install a relay to prevent this. Now If someone uses a stun gun on my car, I don't see how a diode on my neutral sensor wire will do anything to help prevent the shock from getting into my ECU since the neutral sensor has no output when the ignition is off, and because she'd be in neutral anyway. And if all hell broke loose and my ECU were to see a neutral when I wasn't actually in neutral, what would go wrong? Nothing! People have already fried their neutral position switch already? Now thats what I call hokey pokey!! |

Besides, it takes all of two minutes and 20 cents to wire a diode! I actually wired two, and fused it, for a little extra insurance. And netZ's suggestion to test it occasionally is a good one; I do it regularly. On the other hand, if the diode opened completely, the neutral protection wouldn't be there anymore. That's fairly unlikely, though, and I'd rather protect the expensive ECU circuitry. josh |

can't speak for all, but my alarm came with 2 diodes to go with the hood pin, so you may not even have to buy one.

I'm not an engineer but I know a faulty MAP reading would be a much more likely culprit for bad idle than a neutral sensor. Regardless, it doesn't matter. If you car ever gets hit by a stungun, you'll be glad you installed diodes!

I installed my alarm/RS last night. Easiest install EVER. Even in the dark
thanks for the great instructions! |

Thanks for the detailed instructions. I'm going to take it to a pro to install. The shop did have one question though. Does the stock neutral position wire prevent the car from starting unless it is in neutral? What exactly does the stock system use it for? Will a WRX start in gear with the clutch in? Most likely it will - I don't know since I'm still waiting to get a 04 wrx. Thanks!

Not sure what the ECU needs the neutral wire for, and who cares really. It works, that's all the shop needs to know. |

Just to be clear on The OEM alarm. i would like to completely remove the alarm before installing the aftermarket system. Unplugging the horn and removing the wiring from the glove box to the center console is straightforward. When I remove the starter and horn relay from the steering column area, I will have to jumper two of the wires in the starter relay plug in order to still have current pass to the starter switch. Is this correct?, and if so what two wires do I need to connect. I'm sure that when the car was new there was a plug in there that jumpered the wires, although by now this plug is long gone. I looked up in the dash in the hope that the technician might have left it up there in case the system was removed, but it turns out not to be the case.

Yes, I understand that but you didn't read my question very carefully. The cars that don't come with an alarm come with a jumper on the plug that the oem alarm starter kill relay plugs into. When I remove the relay, (following the instructions) without having that factory jumper I will have to know what two wires on the plug have to be jumpered together. If anyone has the pin layout of the plug under the dash it would be quite helpful.

anyone else with a remote start toasted the fuse to the ECU?
I did. I don't know if it has anything to do with the alarm or not. |

can you give us more info? ie. when does the ecu fuse fry? during remote start? when you arm the alarm? disarm etc?
what wires have you tapped off the ecu... neutral position switch, tach wire, coil etc? do you have any other non-subaru electronics tapping into the ecu? uni chip etc etc... thanks! netZ Quote:

it popped when I was just driving, no remote start.
nothing else tapped in, just the neutral wire, and it's diode isolated. |

just a few more questions, how often has the ecu fuse pop since you've installed the remote start? if more than once, try disconnecting your neutral wire off the alarm brain and see if the ecu fuse pops. if it does, you may have some other issue. this will eliminate the possibility that the remote start is causing your problem.
let us know how it turns out. netZ Quote:
