Alarm voltage problem

I'm trying to install my keyless entry system on a 2000 Dodge Stratus but I'm kind of stuck. I found the WHITE/ green wire that controls the door locks and measured the voltage when I locked and unlocked the doors which was 6.3 V and 2.45 V. I also measured the voltage outputted by the unlock and lock wires on the alarm module which was .63 V. I know that eventually both wires will connect to the same WHITE/ green wire but I first need to get the voltages to match right? Where do I go from here, do I need a transformer to amplify the voltage outputted by the alarm module? Thanks

You need to hook up two relays with resistors and have the alarm pulse the relays. (negative pulse from alarm) I believe they are positive door locks and you would need to set it up as follows relay#1 85 and 87 -12V     86- Unlock(brain) 30- 2.7k resistor (and then to WHITE/ green) relay#2 85 and 87 -12V     86- Lock(brain) 30- 620 Ohm resistor (and then to WHITE/ green) GOod luck!

Hey thanks, I'll give that a shot
