"Cut" wires under hood of new Class C Ford chassis?

Thanks. Yes, I'm installing as it says....it does say "if wires are run front to back of the motorhome, use that wiring. Otherwise install new wire from rear to front."

Everything works (lights, invisibrake) right now...the dash indicator on the motorhome is my last step before a true test drive.

I suspected as you said that "probably not connected to anything". Just wondered if anyone knew for sure.
