keyless entry, mitsubishi colt ’93

Hello

I'm trying to install a keyless entry kit a bought on ebay. This is a kit with 2 acuators, a relay and transmitters etc.

I have already mounted the acuators in the doors, but I can't figure out how to do the wiring.

This is the install manual: https://www.blackwidowsecurity.com/installPDF/BW852%20Install.pdf 

As I could understand, I have to connect a 12 volt source and ground to the relay box itself. And I need to hook up two wires from the relay to 12 volts (for the acuators). I followed the "adding acuator" diagram in the install manual.

Can I connect the 3 wires to the constant 12 volt wire at the ignition harness, at the same spot on that wire? Or must I connect them directly to the battery?

The acuators have to wires, one green, one blue. Where do I connect these on the relay? Should I connect the two green wires to the GREEN/ black wire on the relay and the same with the blue wires?

And what should I do with the Ignition input wire and the Parking light output wire on the relay?

I hope somebody out there can help me, I really want this thing to work :)
