I have a 2004 Dutch Star that I am not getting tail light to the 7 way plug on the motor home. I get blinker and stop lights. I figure it is a fuse but unable to find it. I email Newmar with no help except to give me Freightliners phone number. They told me there should be a fuse panel not sure where it is and sent me a diagram of it but can't find the panel. They told me it should be close to the battery box but my drawings of where all fuse panels are doesn't show one near there. Any help would be appreciated.
