i know it arms/disarms with lockunlock through resistors, but for disarm no unlock it says to single pulse the unlock wire. does it need to single pulse through a 7.2K resistor or just straight ground? haven't touched a cruiser before

A negative pulse through a 7.2k ohm resistor will disarm on the first pulse and unlock the doors on the second. You must use a relay to provide a true ground for the circuit to work.

just looking for the disarm no unlock to remote start. hoped that the status out through a resistor would work but guess not then. not strong enough ground to just disarm eh?
