thankyou for the information :)

will this unlock/lock the drivers door or does it need a motor installed?

wonder if this info is true for aussie models as well. hope so! (left side i mean, as i am pretty sure its on the right side for me, the module i mean.)

thankyou!!

If you have power door locks already, this will trigger the system and no motor is required to be installed. Just look for a module with a GRAY plug to the left of the steering cloumn for the right hand drives.

You can also listen for the clicking sound of the lock relays when you hit the lock and unlock buttons on the door. That will lead you to the module for the door locks.

At the moment I need to use the key, but when i use the key in the drivers door, all the door lock or unlock.

I was thinking i would need a mtor in the drivers doo as its always moved/switched by the key motion.... Not by the door circuit through out the car....

I thought it mayb lock/unlock all door except the drivers...

also, would the alarm, or should the alarm be active while in turbo time mode and remote start mode?

i can walk near the car or shake the car when in either mode, not very well protected considering the car is running!!

cheers

another thingm can you please describe how to wire loom H4 (door lock/unlock)

I cant find instruction anywhere in the install manual for H4 except that the 2 wires seem to have both polaritys..

H4 loom=

GREEN (-) LOCK (+) UNLOCK OUTPUT

BLUE (+) LOCK (-) UNLOCK OUTPUT

which wires do i use to connect to the wires you pointed to Jeff?

On my 2005 WRX STi I just used the antenna that comes with the 556U. I would suggest doing the same.

To interface with the Neutral Position Sensor wire at the cars ECU:

I would connect the cars NPS wire to the hood pin input on the remote start. The NPS wire shows a solid ground when in gear. The remote start will think the hood is open, and will not attemot to start the car. If you arm the alarm with the car in gear you will get an indication that the hood is open.

You will need to add in a diode coming from the hood pin, and another diode on the wire coming from the ECU to prevent the circuits from backfeeding into each other. I hope you understand how diodes work. Or you could just connect the NPS wire in the car to the hood pin input of the 791xv and not use a hood pin.

Do not try to have the NPS wire trigger a relay. It is not strong enough of a signal and you risk burning out that circuit in the car if you do.

Thanks everyone for your replys, they have all helped!!

JWorm, why is there a need for 2 diodes? I plan on putting one between the ECU and the hoodpin wire...

Why would i need one between the alarm brain and the hoodpin, i think this is what u are talking about? (if not where do I use the 2nd diode?)

what does the 2nd diode protect?

thanks for the information, I am glad i read your post before only using 1 diode.

cheers!!
