Instead of tying the 10 gauge wires at the timer, pull the bracket out that the timer is attached to and connect a new wire at the terminal strip on the back along with the incoming wires. If there's no strip, connect a new wire to the incoming line and that will go straight to the mercury relay "in" with another wire from the mercury relay "out" straight to the motors (or fuses if it has them). The old timed load that went to the motors will now go to one terminal of the mercury relay of the coil, the other gets a common (white) wire tied into the wire nut already up top.
