Wiring help for trunk mount battery

Well I justed smoked the ford relay. Car died idling in the driveway and the relay was smoking. Ugh!

I have the 4 pole cutoff switch, cant I just run the (2) 14 gauge wires from the little posts on the switch and cut the blue ignition wire out of the bulk head and attach it to each pole? So when i throw the switch it cuts the ignition?
