I am replacing the Limit Switch (025-35381-000) on my Coleman DGAA077BDTA furnace. I do not see any marks indicating that there is any polarity to the switch. Does it matter which of the two wires connects to which plug on the limit switch?

Thank you.

If you have a 2 wire limit it only has one circuit that it takes care of. Which wire you put on which side will make no difference because there are only two wires to start with. If the part had 3 or more wires then it could be a problem hooking it back up without knowing which wire went where. You asked a good question so hook them two wires on to the limit and check the furnace for proper operation.
God, grant me the serenity
to accept the things I cannot change;
the courage to change the things I can;
and the wisdom to know the difference.
