remote start keyeless entry

ok so I am putting a remote start in my honda civic 99 dx, I do not need a bypass module since it has no factory security system. Now I pulled the remote start from my last car which had a bum 2 way system, I just bought and replaced the bum one with a command start 2 way that had door lock/unlock & trunk release added to it via this add on module. Here is where I am in need of help, The module that plugs into the remote start worked without having to program it no hitches when I removed it I labelled the wires and I know what all but one are for. There is no means of identfying the modules brand and there is nothing on it no numbers, stickers etc. So I have in order a Purple wire which is constant 12V+ a GREEN/ blue wire which is door locks/unlock and a brown which is trunk solenoid, and a white wire which I am assuming is ground (this is the one I am unsure of) so if anyone has any ideas here let me know.

I am assuming this 'add-on' piece is a relay pack of some sort. What was the make and model of the 'bum' system and what is the make/model of the command start? Can you post a picture of the 'add-on' piece?Installer, IT support, and FFL. I need less hobbies.
