Verify all wiring with your meter before making any connections!

 Would you have wiring information for the rear defroster?
Thanks

 Thank you for the wiring information. I have an idatalink ads alca module hardwired to a python 4106 remote start. Remote start is working well. When unlocking the doors the alarm is deactivated. When I lock the doors the alarm does not reactivate. When I try to open the trunk the alarm goes off. Do I need to double pulse to deactivate the alarm?

 I have a question about the disarm no unlock. Do I use the disarm output on the remote start to trigger two relays. One relay going to the push to start and the second to the immobilizer?
The immobilizer has three pins:
 Pin 1 12volt
 pin 2 data
 pin 3 ground
 Pin 2's wire is cut and the idatalink is connected to each wire end.
 If i need to send the disarm signal to the immobilizer, which wire is it connected to?
 Thank you

 Volvo wiring diagram shows rear defroster wire at the cem behind the glove box. When testing the wire, it goes from 12 volts to 0.3 volts and stays there. I understand i would set the r/s to latched defroster but am concerned the voltage does not drop completely to 0. Would I still set it up as a negative trigger with a relay from r/s?
Thank you

 I would like to wire the rear defroster on my volvo. I have a python 4106 remote start. I metered the wire coming from the CEM (yellow red C2:2) and found it rests at 12 volts and drops to 0.3 volts when defroster is activated. It seems to work like a negative trigger except i am concerned  about the the 0.3 volt reading instead of 0. Is this a problem or can i use a relay to trigger this wire from the remote start?

 You can take the yel/red to 0-volts. It will be fine.
 The .3 V you see is the result of low (in this case 2.4 ohms)internal resistance of semi-conductors. They are not zero ohms resistance to ground.
