How did you reslove it?

Hi Mark,
Does your truck still have the factory horn relay installed?
If so, those dark green and black wires from the harness should have a 2-terminal plug that plugs into the relay. The dark green wire is the output from the relay that would have gone to the original horn. So all you should have to do is locate the other end of that dark green wire and connect it to the replacement horn.
The factory horns were grounded via their mounting bracket to the radiator support. But many newer / replacement horns will have 2 terminals (power and ground). If you get one of these, simply hook the dark green wire to the horn's power terminal and add a ground wire to the other terminal.
