Need pics/info Trc-920

So I'm finally about to finish my buddies box while I'm at work, to keep my mind off of things, but ran into a problem, the Antenna wires...

There's two wires, but three spots to plug them in at, I tried different combos, but each one makes the radio sound different, I don't want to blow something, does anyone have a picture or know which prongs the wires are supposed to be on?

Thanks in advance!

Would it help if I just took a picture of the three possible spots, for the two wires to go to?

Sorry don't have pics of this section. But one will be for FM other for shortwave. Testing each will not do damage unless you ground to something
