Stereo & Electronics - Remote Start Wiring

I want to use the lock pulse from the BCM to activate my remote start so the doors stay locked while the car sits idling. I currently have the unit hooked up to the red/black door lock input wire at the BCM, but this doesn't seem to trigger the remote start. Should it instead be hooked up to the gray wire which is lock all output?

Also, what wire am I looking for to hook up the neutral safety switch?

Thanks.

The red/black wire provides lock input from the inside door switches only. That kind of defeats the purpose of "remote" start. You'll have to use the gray output wire from the BCM to get a pulse when using the key fob.

The bigger question is how are you going to lock your car without starting it? Sure, you can manually slide the locks on each door individually but any use of the power locks (key fob or inside switches) will engage your remote starter.

Besides, doesn't your remote starter come with all the safety features to prevent theft? For that matter, doesn't your remote starter come with a remote?

should be able to set pulse on your remote start so you have to hit lock 2 or 3 times. ground the wire for neutral saf switch

Glad you stepped in here to help. I thought I might need to use the gray wire, some of these online guides identify the wrong wire.

I am using the DEI module so I should be able to set the module to set off the remote start after three lock pulses. I just don't want to have the car unlocked and running while I'm not in or near the car.

Isn't the point of that wire to not allow the car to start in gear? I know the car does this already if you tried to use the key while in drive or reverse. The remote start doesn't bypass this safety feature correct?

definitely, want to properly wire the neutral safety switch wire, once new a guy with a civic SI hatchback when honda brought them back in 01-02 and he had it bypassed and it was a manual trans and he cranked it one time and the damn car went there the parking lot and hit a bunch of cars, Yet another reason to use the PARKING BRAKE and not just putting it in gear to keep it from rolling.

Also unless your doing some weird bypasses, remote starts auto kill the engine if someone depresses the brake pedal without the key in the ignition, so its not like someone is gonna hop in it and drive off because you left it unlocked.

After thinking about this a little bit more, I will probably bypass that neutral safety switch for a couple reasons. The first being that you can not get the key/fob out of the ignition with the car in gear, it has to be in park. So having that feature hooked up is probably a waste of time.

I hear you on the danger with a manual, but I have an automatic so I don't think there is quite the same danger.

Not doing some weird bypass, but if I'm getting ready for work in the morning and want to get the car warmed up, I don't want to activate the start with an unlock. I'm not worried about it running and someone jumping in and driving off, just don't want the car unlocked for someone to go through while I'm not around.

I've had remote start on 2 cars I've owned in the past, but they where hondas that didn't have any alarm so I got the Viper with remote in the first one and the Hornet? (can't remember) on the second one both I believe are part of the DEI company, So i've not run into your issue since they either had a dedicated button or button combo to activate the remote start. Could you program it so you have to hit like lock and hatch at the same time, maybe a "dual signal" would prevent either individual thing from activating, is that possible, thats how my second one was setup?

I'm pretty sure I'll be fine with the door lock method that I'm going to use, not sure the DEI unit will accept two signals like that unless I set up some kind of relay.

Thanks for your help.

or what about a single hit from the hatch button, since you have to hit that twice to trip the latch?

The problem is that the BCM produces no output from a single press of the hatch release button so you would have no way to determine that it had been pressed. Not to mention that the car would start when you wanted to open the hatch. Besides, having a multi-press setup helps prevent accidentally activating (like pocket dialing).

If the remote start module can be programmed to require multiple pulses to activate then the lock pulse seems like a good idea. Just be aware that the inside switches produce the same pulses on the gray wire as the key fob.

Thanks WhiteBird. I'll change the wiring up tonight. I also realized I have to have the neutral safety switch and hoodpin switch grounded even if I won't be using them. So hopefully once I have all this squared away it should start working.

im looking into a remote start setup right now. So im confused on all the tech talk. Is there a go to kit for this? I live in an apartment complex with garages right outside the complex about 50 feet from my door. Ideally I want to be able to start the car while its in the garage before i open the garage door so there is less noise when i leave for work in the morning. Any ideas?

Can you use your key fob from that distance to open/unlock the doors? If so you can use the kit I have. It is the DEI Avital 4003, you can also look on eBay for the DEI 561T. The latter is an older model, but it works the same for my purposes. This is technically an "add on" to the factory keyless entry. Basically, I have set it up so three presses of the lock button will start the car. I went this way because I wanted it to be simple and keep the OEM keyless entry system. I think most people tend to go with a setup that replaces the factory keyless system and alarm, usually with a new remote that has a dedicated remote start button.

Hope that helps.

go with a stand alone FM two way remote starter with or without the alarm.the range is unreal and the LCD screen will let you know whats going on with your car from a unseen distance.
