The wiring harness I used came out of a van, and if I remember correctly, there are some subtle differences between my harness and yours. The transducer has an extra little component (a valve, maybe?) mounted to it, and so there are some extra wires for that. I don't know if the wiring under the dash is the same or not.

On my van harness, all the wires run from the transducer, through the firewall, to the brake switch, to the turn signal lever, and to the fuse panel for power. Right after the harness comes through the firewall, there's a Y. One leg of the Y contains a vacuum hose for the vacuum kill switch, and a couple of wires that run to the electrical brake switch. The other leg of the y contains a pink wire that runs to the fuse panel for power, and three other wires that connect to the turn signal lever (blue, brown and green). That's what your dangling column wires should plug into.
