I just got a replacement inductor fan for my Ruud 90+ furnace and the wires are in a different place. On the old fan, one wire came out of the middle of the motor on the top and one out the bottom of the motor in the middle. On the new fan, they both come out the back. How do I tell which goes where? Will I burn out the motor if I hook them up wrong?

One wire says "switchboard wire" and the other says "body". Still unsure of which goes where. The old wires go to 2 plugs in the bottom of the compartment, one of which has two wires that go to a box with other wires attached. Is this the "switch"?

Couldn't wait for heat as it's -20 here. Hooked up the switch wire to the little box and it worked so I guess that was right.
