1999 nissan laurel alarm wiring

1999 Nissan Laurel C35 E-HC35 Grand Saloon Hi I'm installing an alarm for this car. I can't find the factory door trigger, indicator lights, and central door sensor. Anyone has the experience please help. Thanks Bill

I finally had to take pity on you.  That vehicle was never released in Europe or as far as I know North America. DEI might know from their Japanes affiliate but the other option would be to look at the crib sheet on this site for the Altima of the same year and take that as a basis.

Just thought, do you have a door open display on the instrument panel?  If so that's your first two questions answered, pull the instrument panel.  Second what's a  "central door sensor",  I've never heard of one.

Hi Howie Thanks for the info! There is a door open display. But does it work in battery mode? "central door sensor"..I made it up, I mean something works like the door open display on the instrument panel in the battery mode. Oppose to the switches on each door for open/close. The car automatically locks all doors once speed exceeds 20kmph. I wonder if I can use this module to lock all doors instead of install another door lock actuator in the driver's door? Where do you think it's located? This is the first time I install an car alarm. Please guide me even my questions are so basic.

That light will work all the time though it only illuminates when the ignition is on.  You need the feed wire that goes to GROUND (NEG)  when any door is open. Indicator light feeds will also be in the instrument panel plugs. You will have door lock trigger wires either in a central processor or in the loom coming from the drivers door, assuming there is a motor in the driver's door, do you have an existing keyless entry?*  If so you already have an actuator. If 1 wire for lock and 1 for unlock. Grounding each in turn will give you lock and unlock. You shouldn't  need any extra components, nearly all alarms have basic central locking outputs, i.e. 2 wires, neg going. If you can't  or don't programme the alarm's autolock facility (and it would help if you told us what brand) your existing door lock at certain speed will not be affected. * Come to think of it you must have an existing actuator in the driver's door otherwise your driver's door wouldn't lock with the speed dependant locking system presently on the vehicle. You will have to mount a hood contact switch, the trunk contact switch would either again show up as a trunk open warning light or pick it up at the micro-switch in the trunk lock mechanism
