Well it started when something hit a box underneath on right side of truck below floor behind right front tire. it cause fuel pump to quit and all lights in rear and burned out fuses. fixed fuses with new fuse box repaired wires underneath floorboard which i dont know what its called but it looks like a alternater and it controls fuel pump/all lights in rear / causes turn signals to malfunction even after fixing the problem and every time i hit a hole or something in the road it would start acting up .I have tried everything to make sure it dont cause me more problems but everything in the rear lights work other then reverse lights but the thing that started all my problems from that time on slowly are making more things to show problems .My question is why would anyone put electrical part in that spot that can get damaged by anything to make problems then and non stop after .
