Start by checking the fuses. The running lights have a different twelve volt feed than the headlights use. Were there any blackened or charred terminals on the old light switch?

Which model do you have, and what is the correct engine size?

I am swapping the fuse box with an updated version. The engine is a 351 did not see any bad wires or terminals I will double check that.
