Need some turn signal school

Well how do you think I've had it for 4 years!??
So my next question is I've got this all apart and grounded my test light and obviously when I hit the horn one that makes the horn go off LOL (ouch my head) but with the ignition switch on I don't get anything out of any of the signal connections that are there underneath the steering wheel in the plastic thing?
I'm wondering is there a way to just put a fused wire directly to the signal switch?

I refer you to post #11.
