if you use those 2 wires to switch 2 relays that should keep things safe.
neil.

Thanks, but what your thought on using both wires to connect to the same trigger plug on 1 relay?

My main fear is not knowing what is before these 2 wires on the plugs which shouldnt have power. I am going to get my relay installed next.
