installation of aftermarket keyless entry

Trying to install an aftermarket keyless entry system on a 2003
Caravan. I have power door locks factory installed.
The BCM for this vehicle has 5 ports, it is a one wire door lock
system, everything I have found on the internet say to use the
white/green iis this color light green or dark green? Dodge changed
the entire wiring system for 2003 so I need specific guidance, so I
don't fry the BCM. The other 2 responses are great but no luck
getting this thing to work yet.

the RKE box wires at. I have power door locks factory installed.
Any help would be great.

I have done this. It is under the fuse panel, in the computer wiring plug. It is a very small wire, and resistors need to be hooked to the sigle wire from the remote starter. I had to go to a local shop for the resistances, but it wourked like a charm.

Yep. Look up under the dash against the firewall and you'll see the BCM with 6 plugs in it. The plug you need is the 3rd one from the bottom. MAKE SURE TO CHECK WHAT YOU ARE DOING AND TO USE RELAYS WITH THE CORRECT RESISTANCE. If you fail to do so, you will burn out the power accessories in the BCM and it is $2,300 to have it repaired.
