Backwards battery?

I must be the only dummy but. My vehicle had starting problems. I suspected the terminals were at fault. I replaced them which resolved the problems after all yet I made the dumbest mistake to mishandle the battery and caused reverse polarity on the vehicle (negative on positive; positive on negative) momentarily. Vehicle starts with no trouble only now the tail light, brake lights, hazards, a/c, wipers, and instrument cluster do not respond. On the instrument cluster the high beam indicator functions when the headlamps are on high. I checked the fuses under the dashboard and they are operational, I even went as far as replacing all of them. I partially replaced whatever new fuses I had left to the fuses next to the engine compartment. Every site I found familiar situations discussed the diodes in regards to reverse polarity. Need help! I appreciate your time. Thank you!
