I'm going to install EasyCar Alarm with push button start E772AS, And there are some things I do not understand or simply can not find. 1 - door unlock and door lock, in installation guide they ask you to look for wires that negative when doors unlocked or lock, I found two wires that give plus when doors unlocked or lock, I wonder if these are the wires or not (or do I need to add a Relay)? Or I need to cut some wires between the door motor And unlock and door motor And lock? 2 - Can someone explain to me what is key trigger plus and minus, or how I find them? And all the rest I think I have , I hope at least.

your lock and unlock wire should be as followed Lock WHITE/ Black At Black and Gray Conn At Left Of Steering Column Negative Unlock RED / Green At Black and Gray Conn At Left Of Steering Column Negative You should not need Relays for a negative output as for the key trigger its probably the keysense KeySense Green At 2 Pins Connector At Steering Column Positive if your alarm have a positive keytrigger wire or a jumper to change it between + and - then you can hook the wire to it. if not then you will have to use a relay to switch a - to a +

Many thanks for the information I will check it.
