no central lock since alarm

Car is a 2006 Honda Stream(wiring similar to Honda Civic of the the same year) I got my alarm installed but since the installation my Central Lock no longer work. The guy that did the installation cut a wire in my drivers door saying it was having an effect on the alarm. It was cut from a harness with three wires and I was told the car has a negative trigger from the central lock. I want to get the central lock functionality back(the alarm currently locks and unlock the door). How can I do this?

He must have cut the trigger wires from the sloenoid in the driver's door, civics of that generation do not have a rocker switch, i think i wire those with a pair of relays. It's should be a simple repair job if you have a few small tools and some common sense, we can help you, or you can take it back to him, but seeing how simple this situation is, taking it back to him might not be the wisest idea.commit your way to jehovah and he will act in your behalf. psalms 37:5

I guess that's what he did. I don't want to take it back to him as he is saying it cant be done any other way and I know it can. Which relay diagram should I use? I am willing to attempt the fix myself
