96 passat door locks

Hi ive read all the instructions and im pretty much done with install the only problem im having is that i need a diagram for a double pulse to positve to unlock the doors any help would be appreciated

almost forgot alarm is negitive trigger

Set your alarm to double pulse. Lock relay ... 86 12volt 87 12 volt 85 (-) lock from alarm 87a not used Unlock relay Same, except 85 will be (-) unlock from alarm. Oh yeah....this is assuming your alarm has a double pulse setting....which I would be able to tell if you posted the make and model of the system.

Might be wrong here but surely the locking system is low current neg   picked up in the doors.

ok i guess i wasnt clear enough the alarm is prestige aps-25cl doesnt have a double pulse feature what i need is a diagram to double pulse to unlock and the alarm is negitive pulse and the car is positive pulse

Sorry, use a dei 528t timer relay to send up to 15 secs, this will close your windows and roof and change the polarity, for the unlock you will need 2 relays, one to change the polarity and one to add a second pulse, wire as follows:- unlock output to 85, 12v+ 2amp fused to 86 and 87, send 30 to lock wire. Before the lock join to 86 on second relay, fused lead from 1st relay to 87, 85 to ground and 30 to lock wire. Diode across 85 and 86 of both relays with band towards 86.  This is an update of my PM a few minutes ago. I still can't believe the unit only has neg lock outputs.

ok i used this setup and second relay stays activated and rolls down any help??

rolls down the windows

Wait at least 20 secs to disarm, if you do and they still roll down, check the relay op to see what's latching it.  You might need diodes, band towards the alarm to stop back feed. On Mk lll Golf /Passats if you hit unlock while the close timer was still working, the windows reversed. If this doesn't work, there's a UK comany called Heart electronics who make a relay for this purpose, it's about $20
