Hi John, welcome to justanswer.com

If this is a replacement, it will connect to the same two wires from the old one. Since it is AC Voltage , it soes not matter which wire goes to which lead.

Expert:  ProGrade replied 17 days ago.

You would make the connections wih wire connectors comnonly called wire nuts sized to the wire.

OK, so I've been having trouble with this furnace for over a month. The 2 upstairs thermostats dont work even when I place a jumper over the red and while wires. I replaced all of the wires and thermostats but still nothing. I currently have 2 brand new 24vac transformers powering a new aquastat and thermostats. Where is the problem?
Expert:  ProGrade replied 17 days ago.

That's a good question. You did not mention thermostats in your original post, you only mentioned solenoids so I will opt out. Good luck with your repair. Perhaps another expert will offer assistance.
