ok here goes it

i looked at the vehicle wire and all the tech i could find on this issue.

98 Audi A6 wiring states : door triggers = Red / Yellow - Driver Pillar Harness

ok i found that wire....when metering it with my multimeter this is what i got at open meaning when the door is open the trigger reads 12v which is fine.... now when i close the door and wait for the dome light to go out.... it reads 1.09v.... constantly...

so am i doing something wrong here.. or is this the wrong wire ??? or is there something wrong with the door triggers ????

i'm assuming that if it's constantly reading 1.09v closed that there is huge current draw constantly and would kill the battery in time so... there would be something wrong with the door trigger wire ???
and with compustar it shows the door always open.
i've also tried diode isolating the wire as well but that didn't help ..

next.... factory disarm - brown / green... i could not find this wire anywere... so what i did was used the factory disarm wire compustar ( orange / white ) and taged it with the unlock wire ( blue ) and hooked it up to the brown / yellow wire of the audi... is this correct ????

You will find separate door triggers in each kick panel, I believe BROWN / white and BROWN / yellow, they shut down immediately the doors shut, diode isolate and that's it. Therer are two locking control systems on that car. Be very careful here, one circuit will lock and unlock as your driver door switch, the other dealocks and closes the windows. That's the one to look for. It's safer to take them off the combined vacuum pump/alarm in the rear.

Look to vehicle wiring on this site it will answer your second question.

turns out i gotta go to the factory alarm harness and get the wires indipendently.

i've found so far :

DRIVER FRONT DOOR - GREEN / YELLOW <- this is correct
PASSENGER FRONT DOOR - RED / GRAY <- this is corret
DRIVER REAR - BLACK / RED <- this is corret
PASSENGER REAR - BLACK / PURPLE ????????

can anyone fully confirm this ?????????
all ( - ) trigger

i found this in another post however the passenger rear is not workin so is this wire correct...

Probably wrong here but on A3/A4 there are only left and right triggers, not front and back. Is there a rear dome light? Does it shut down immediately when the rear doors are shut? If so use that for the rears. All VAG (VW, Audi Seat Skoda and Porsche) use neg door triggers although some A4's in the 90s used a pos trunk trigger.

Ref the factory alarm harness, I already told you that.
