I have a 2006 fummins 6speed. Have no reverse lights. Can someone tell me where the fuse is for them bc mine didn't come with the owners manual and if not then what to do. Thanks

 

Check bulbs to make sure they are not both blown. Fuse list below for your reference. There is a neutral safety switch drivers side of trans that it could be also.

Mine didnt have the owners manual. I have checked all the fuses and bulbs there all fine. I located the switch on the trans how would I go about testing that? And then what to do after that?
