The passenger door unlock wire should be for, if you need a second pulse to unlock all you doors, i.e. if you can unlock you driver's door seperate from the rest of your doors you then need this wire to be connected so that all your doors will unlock with your alarm disarm.

The door trigger wire is for if someone opens one of your doors the alarm will be triggered. You do not need both of the wires. For your car you only need the (-) negitive trigger. It should be a RED / yellow wire under the left side of your dash.

Remember check all your wires with a DMM!

Hi all

Please help! (Utra start 4500)

I can't figure out why the my vehicle sometime start by itself.

First of all, the temperature sensor is not installed and the Timer Mode is not set to on

I have tried to disable the Timer Mode many times (if it is on) but that didn't fix the problem

I came home the other day and found the van running, so turn it off by stepping on the brake

According to manual, the Timer Mode will automatically disable itself after 24 hours

So I don't what cause it to start.

Thanks all
