Making the sunroof the 4th channel

• 86 : 12 Volt Constant
  87 : Ground
  85 : Alarm input channel
  30 : Goes to sunroof ( GREEN/ RED ) This is to close the sunroof
  87a: NOT USED

Yup !! Whatever your fancy

Try this:

• 30 : Motor leg of sunroof
• 87a : Switch side of sunroof
• 87 : GROUND
• 85 : 12 volts CONSTANT
• 86 : Alarm(-) output

The sunroof wire requires a (-) signal not a (+). The Bulldog tech guy was telling you that the relay configuration for the sunroof required a (+) siganl to close the sunroof. I hope that you didn't short anything out ?!?! Make sure that before you hook up the wire to the sunroof from pin 30 you check the polarity of the output and double check the polarity of the GREEN/ YELLOW and see if it is in fact a (-) input wire.

Thanks for the reply...I just have a question about the last 2 things you said:

1.  For checking the "polarity of the output", do you mean to probe the alarm's output

2.  Then, I can probe the GREEN/ YELLOW wire, and I should get a (-) polarity as well?

3.  Plus, I'm assuming that when probing both of these wires, I should be getting

Thanks!

1. I mean make sure you probe the output of the wire on the relay, pin 30 to make sure that it is infact a (-) signal

2. YES

3. No you need the car ON when testing because the circuit has no power when the car is off. Turn key to the ACC position and test the wires when you press the switch and make sure that it grounds out when pressed. If it does then you have a (-) trigger and the above relay configuration will work.

Ahh, just to conclude this episode...

It turned out that the wire for opening the sunroof needed a positive

So I did hook it up the way bulldog suggested, and voila, it worked...

85 --> 12v

Finally:)  So, in the same manner, can I hookup another relay to do
