There is nothing that says you can't. That being said, we use plastic to avoid the possibility of shorts and other electrical issues. The new control system isn't as touchy as the old one was, but make sure you electrical is clean and has no exposed wiring near metal.

We've lost a few expensive components over the years by having PWM cables short or by having insulation wear on other wiring that has caused issues. A little bit of planning can avoid all of that.
