Water temp switch

Just finished adjusting the valves car was running perfect til she got completely warmed up. Got that rough idle and I figured it was the connector on W/T switch - son as I touched it turned to s--t.

No where to get a new connector til Monday - wonder it I can just cut the end off and spice the wires together - don't need the warm up injector right now and with the open circut it is always on.

Thoughts.
