Ground wire goes where? Under dash?

I am still unsure where to connect the little end of this wire. I tried touching it to a couple places on the column itself and nothing seemed to change? (meaning I would hit the horn but still dead).

What is more interesting, is I dont think this is the steering column ground, because the column support the big end connects to, has a large rubber piece that is decoupling the column from the support. I do see a small green wire (obviously installed after the fact) which is wedged into a Fuse, then goes into the steering column. what kind of nonsense is that?
no horn, no light on column. Those are the only 2 things that are on the column,. The turn indicators work. Driving lights work (ones mounted on the trunk). I dont seem to have any backup lights? though there is a plug on the back of the steering column for what I thought was reverse lights, which was unplugged,. I plugged it in and it gave me the Driving lights on the trunk.
