Anybody in here installad their own alarm????

[Guest speeddy]

I wonder if there is someone in here that have installed a car alarm to their own supra that can help me with a little problem that i have.

 

Everything is working ok with the alarm but it will not unlock the car when disarming the car that it should do.

I read somewhere that there is a wire somewhere that I should cut or something so the car dont think it is a break in.

I have done my own, but it won't be certified in the UK, however you are in international member.

 

Which alarm are you using. It sounds either like

 

a) The alarm isn't sending the unlock pulse

or

b) The alarm isn't connected to the correct section of the loom

 

There are plenty of wiring diagrams available on here to confirm which is the correct wire in the loom. It will be one running along the passenger sill usually.

I am using a 2way fm car alarm that i bought from ebay with remote starter.

It sends the unlock pulse beacuse if I have the door open and lock and then unlock again it will open. Wierd.

It is just like the car has a way to stop it from being open if you dont unlock the car with the key.

You need to connect 2 wires from your alarm to the fuse box in the drivers footwell.

 

One wire will unlock , the other will lock the car.

 

I've got the facelift car, on mine it's the blue connector at the bottom right.

 

Red/green wire goes 0 volts to unlock the doors.

 

Red/white wire goes to 0 volts to lock the doors.

 

You should check them with a multimeter first to see if yours are the same colour.
