Keyless Remote Wiring Question

I bought an anfetmarket keyless remote system and I am trying to figure out where exactly to connect the door lock/unlock wires.

I've read a few posts on this subject and can somebody tell me exactly where these wires connect? Do I need to buy some sort of interface with the BCM?

Any help would be greatly appreciated!

I had my remote start installed by a stereo place near me that I am good friends with and yes I had to purchase an add on adapter with it to allow the keyless feature to work with the the remote starter as well.... the keyless is tapped into the data wire at the OBD II data plug under the panel at the drivers knees. You wire the unlock and lock wires from the keyless system to the adapter and it sends the signal thru the data wire to the system computer to have to door locks funtion.
