Need help trying to pass inspection tomarrow! Need to wire horn and rev. lights

[Stang_ROTY]

I have a 93Gt and need some help wiring the horn and rev. lights so I can make an attempt at passing inspection. I looked in the Chilton's manual and the thing was useless. I have an air bag, too. I have what looks like a horn mounted underneath the drivers side front end but there are no wires attached. I need the reverse lights cause that's mandatory for the safety inspec. and that should be a little easier. Thanks.
