The fuse box on my car has fuse holders on each for fuses to clip into, except for the the 20 amp accessory and 20 amp emergency flasher fuse locations. They each only have one fuse holder. Is anything missing? Upon inspection from the back, there are no broken wires, or signs that a clip was ever there. I recently bought a grade A used harness, thinking something was missing, and for other reasons. The new used one I recieved is the same. So are there fuses that are supposed to go in those locations? Is it a shared circuit anf no fuse required? Looking forward to your reply.
