K2theM is cool... so far.
Yeah. After doing some searching and some testing; I'll need to do the following:

1. The horn is the Blue/Red wire at the steering column plug, but it switches ground. The Module I have switches live and is normally grounded. So when I hook the module up directly to it the horn blasts constantly. I can get this to work by using a relay that is activated by the module and provides a ground to the horn circuit.

2. Looking through the wiring diagram for the Power Windows, your suggestion is correct. Using diodes would be much better and more compact than the 4 Relay idea I had.
