I visited a friend last week who gave me light strobe siren system kit thing that he removed from a car.

Before people get all legal and stuff I'm not going to wiring it up to my head lights. I'm thinking of wiring it up to something else I'm planning.

But I have a small issue with trying to wiring it up.

Here is the unit with all the bits.

Does any have any idea how to wire this up?
I don't want the siren, only the head light flashing bits.
