Not these, but some solenoids are sensitive to polarity. Some DF's I've seen have a solenoid arrangement where the plunger is in a central position held by a magnet, with a coil on either side to move the plunger In or Out from that central position. Three wire connection.
There are a couple of Lexmark models that it is impractical to unstring 16" of wire harness back to the controller board. Lexmark includes two splice connectors (aka 2-Port Dry Environment, Single U-Element Insulation Displacement Connector 3M Displacement Connector,12-10 AWG,PK100 - 4YT69'|'562 BOX - Grainger) which are a bit large for the area you have to stuff them, and notoriously unreliable. I throw away those splices and solder/shrink the connections. The wires on the Lexies are color coded so you'd have to be even more stupid than me to get is mis-wired. =^..^=
