According to my notes it is just  straight (-).....no resistor.. Hook it up to the factory alarm disarm wire of your aftermarket alarm.

Its at the BCM gray connector  (all the way to the right) pin B3 lt.green. (NEG)- pulse If you do a quick pulse, this will disarm (NO RESISTORS) if you do a vacuum pulse, 2.5 seconds like for benz door locks, it will disarm and unlock all doors.

Your remote start SHOULD have a disarm wire, used for this purpose. To disarm factory security.

you can diode off your unlock wire and that will work. Hooking it up is not neccessary but i would, just in case the factory alarm ever gets armed.
