isn't that cap on the right side of the dryer to connect the rigid line? Should be a separate spot on there for the safety switch. Look at the dryer label and see if you can call those guys and find out. I can't recall the name of the condensor/dryer place I ordered from, but it's on the label there.Mike, your post put your words next to mine. I opened it and see what you wrote.
No, the drier/dryer... (Which spelling is correct?) ...has a cap on the right fitting as seen in the picture.
I'd sure rather put the switch near the firewall for simplicity.
