Door and trunk are negative triggers.

A negative trigger means that the domelight in your vehicle is supplied a constant voltage. That constant positive voltage goes to the bulb and travels through the bulb to the pinswitch in the door or door jamb of the vehicle. When you open the door that pinswitch travels and the backside of it contacts the body of the car. The body of the car is grounded. When that pin touches ground, the light comes on. This is a negative trigger. Since it takes negative voltage to trigger the domelight and alarm.

A positive trigger found on a lot of older Ford vehicles works this way. One side of the bulb was permanently grounded. The other side of the bulb was wired to one terminal of the 2 pin pinswitch. Constant power was attached to the second pin of the switch. When the door was opened and the plunger for the pinswitch came out, it simply connected the 2 pins of the pinswitch together. When the door opened the power pin and the pin going to the domelight were connected together to provide positive voltage to the domelight. Since the positive voltage was applied, this is known as positive trigger.

The guy is talking about his door locks, listen to the old mustard who's the only one of you who's worked these nasty little Spanish built German branded beasties.

Door lock is multiplex, blue white, neg to lock and neg via 1kr to unlock. In the door loom

Under the dash is the body manager with 2/4 doors,+ trunk and hood contacts all neg AND ALL TO BE DIODE BLOCKED 'cause the body manager triggers every hour or so. Getting off the steering column cowling is like making love to a porcupine, the looms are covered with a very nasty, thick fabric cover and the whole job is a back-ache special.

Definately not a DIY job, especially with the questions this guy is asking.

Thanks for clarifying Howie...."triggering" threw us off although I've never seen pneumatic door pinswitch triggers. DOH! triggering types, 2006 vw polo -- posted image.
