Headlight motor and Back-up light problem

[IEatSparkPlugs]

For the headlight retractable motor I'm geussing the problem is the fuse link from the battery to the relay switch #6 but i dont know where the fuse link is, as for the back-up lights, the fuse is good and i have no idea what could be wrong. Any suggestions please (KA24DE 91 240sx, just recently had light problems with turn signals but geussing it was a loose fuse since i checked every fuse and it worked after placing them back in)

if it's a fusible, it's up front in the engine bay on the passenger side.
