nitro bmwx 433 alarm/starter on 99 legacy

Most of the install is complete. My First Alarm Install. I cant get the start function as well as the door unlock/lock to work.

Do I need to connect ALL the wires? And for a 99 subaru legacy L Wagon, how do i connect the door locks so they work. Also I dont know if I'm even getting a tach signal. It wants to start . It turns the on the acc, but doesnt crank over. I have the cars wiring diagram as well as the one i just posted for the alarm. I am very stuck at this point. Any help will be graciously apprecitaed.

No you dont have to hook up "all" the wires. Only the ones that apply to what your doing. The locks on that car should be negitive trigger. it looks like the alarm you have has internal realys so just look at the diagram in your book for negitive triggers. Lots of the other options depend on what you want the alarm to do and if its an automatic or stick. If you dont have a factory alarm you dont have to use the arm and disarm wires, if you do there in the drivers kick. Take a test light and see if the alarm is actrually sending power to the starter wire to start the car. Im pretty sure that car doesnt have any anti theft so it shoud be an easy start. double check your starter wire. The tach wire is a debatable connection, i personaly will not put an alarm on with out hooking it up. Some people are fine using the voltage sinceing option of the alarm (see your manuel there should be an option to change it back and forth in the programming) The best tach wire on that car is on the coil, blue I think, I would put a meter on it to make sure.

I am not familiar with the Nitro BMWX unit but it looks like you have built it relays for the door locks.  Follow their
wiring guide for Type B (-) door locks.  The Legacys lock wires are found in the module to the left of the steering
wheel. White is Unlock and WHITE/ Red is Lock.  Here is a picture :

For the ignition wires, here is a picture of the connector with the wires marked :

For the Tach wire, I usually get it at the coil pack although you can get it from the ECM behind the glove box.  Here
is a picture of the Tach wire at the coil pack  :

There might be some sort of Tach Learn process you must do prior to a sucessful remote start.  Check the install guide
for the Nitro unit.

Soldering is fun!

Also, not to disparage your Nitro unit as I have never had the pleasure of installing one, as a general rule of thumb, any unit that uses the Oil Pressure Switch as an engine sensing input signal is of questionable design and quality.    

For the best results, use a Digital Multi Meter to locate / test all the vehicles wires and properly solder all your connections.

Thank you very much for your advice. I will work on it some more today and get back to let you know how it went. AGain THanks

One more question. Pin 4 : BLUE/WHITE Wire on the 7-pin  connector secondary harness for the remote start. (-)200ma bypass output when remote start. Connect this wire to the interface of remote start bypass module. Do i need to hook this wire to something or not? I dont know where the interface is

And then Neutral safety switch input wire. Can i just connect this to ground seeing as how i dont know where the switch is or the wire thats connected to it

Your car does not have an engine immobilizer system and does not use this output wire.  Newer Subaru's have a transponder chip in the ignition key that would require a bypass module.  That Blue/White wire from the remote starter would be used to control the bypass module on those newer cars.

Wonderful Thanks. Another one to cross off the list. Beutiful. Getting on with it now . Talk to you guys in a bit.

The Neutral Safety Input : Is your Legacy an Automatic or Manual Transmission vehicle?

If you have an Automatic :

Verify that your car will not crank when in any gear selection other than Park or Neutral.  If that test passes then connect the Neutral Safety wire to the Parking Brake switch. This switch is found at the Parking Brake and the correct wire goes to gound when the Parking Brake is engaged.

can you help me find the red and white door trigger wire. Is it the wire coming from the pin in the door

The easiest place to find / connect is at the Keyless Lock module.  That was the top picture in the prior post with the Lock, Unlock and Horn wires marked.  Look for the RED / White door trigger and the Yellow/Black Trunk trigger wires there.  Use your Digital Multi Meter to verify you found the correct wires.

DMM setup for (-) Trigger wires:

DMM set to 20V DC.   Red lead to +12v constant.  Black lead to suspect wire.  DMM should go to +12v when any door is opened.

got the keyless entry to work. Yeahh.. I forgot to hook the ground wires up

Yes, the install guide does not highlight those two relay input wire connections to ground for the Type B (-) lock wiring.   I had to look closely to see the difference between Type A (+) and Type B (-)..............

does the remote starter harness work on the same principle that the ground input wires for ex. Neutral safety and wait to start diesal HAVE to b connected


-------------
SimmpleeDaBesst

my car is automatic and NOT diesal by the way

SimmpleeDaBesst

Neutral Safety has to be connected.  Other important safety wires that must be connected are the Brake (+) and the Hood Pin switch.

Diesel Wait to Start is only used on diesel engines.

Keep looking.  You're almost finished.  It's there somewhere.  (DMM testing procedure previously posted.)
The three references all show the (-) Door Trigger as RED / White.  Connect to Green (-) Door Triogger Input of alarm.

You will need two 1N4001 ( 1N4004, 1N4007 ) diodes if you wish to combine the Door and Trunk Triggers on to the alarms' one (-) Trigger Input wire.  Diode band away from the alarm, towards the car.  Diode info :  https://www.the12volt.com/diodes/diodes.asp
