I have a negative output from my alarm for window-up but the power windows only receive 12v+ when ignition is on. Do you have to buy a special module to do this.

Wire up a relay.

If you are able to install an alarm yourself I would have hoped you could have figured this out yourself.

ok, so i hook up 12v+ and negative pulse output from alarm to coil on relay which when energized will cause the single pole to pivot on 30 and deliver 12v+ to window module as long as negative pulse is coming from alarm.

85- negative output from alarm86-12v+ from car30-window module87a-nothing87-12v+ from car

This will make the windows roll up when you activate the negative output from the alarm...

Put a test light or meter to one of the wires on the window motor and turn the ignition of the car on. Find the one that indicates positive when hitting the switch to make the windows go up. Turn the key off and cut that wire. Then wire up a relay like this:

85- negative output from alarm 86- 12v+ straight to the battery (fused with 40amp fuse) 30 - cut wire (side that runs to the window motor) 87a - cut wire (side that runs to car) 87 - tied to pin 86 (+12V)

This will roll the windows up when you activate the second channel. If you have timed outputs you can set the timer to something like 5 seconds or so. The window motors on the S13 have circuit breakers built in so the timer circuit should work without problems.

However make sure that your negative output isn't the "output when armed" wire. Otherwise you will burn out the motor eventually.

Cleanest way to do windows is to just get a DEI 530T or a Smart window module if you're running a Clifford alarm.

The green wire for driver side and thick red/white for passenger. Both wires are accessed in driver door. The green wire goes to a connector just before motor for driver window motor so you can use the smaller wires that go from connector to motor. Forgot what colour they are. you need 2 relays . one for each motor. don't cross these wires. split the output from the alarm so it goes to both relays. both wires are ground at rest so don't try connecting a positive wire to either or you will get short circuit.
