We need to know what coach you have a gas, Ford or Workhorse or diesel coach, fuses and panels could be different.
You can add this information in the CP location top left of your page your on, in your signature.
I can give you links to help you for other items and maybe a Brochure and Owners Guide if we know year and type coach you have. The owners guide may have your fuse locations another reason we need your coach information.
As a Newmar owner you need this link
and this one
to help you around irv2.
All the links below in my signature have answers for your Newmar.
