I don't know how to connect this to the stock wiring harness

Well go clarify I know it should go back to the stock horn harness but I don't know how to connect it

Forgot to attach the picture

I have connected everything except the circled area I don't know what that goes to

I'm looking for a place that can make a custom wiring harness that can connect to my aftermarket horns it has to be near or in san diego.
