kia carnival, sedona diesel 2005

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.
