92 vic wiring

Can anyone tell me exactly how much of a hassle it would be if I ran new wiring from the back of my car forward? Thanks in advance.

for what?

A 1992 ford crown victoria,

to wire what like what do u wan to run wires to?

I have no brake lights but I have every other light(taillights, turn signal. etc etc.) I have switched out the part on the brake pedal, changed the bulbs, checked the ground and the fuses, still nothing. So I figure it would have to be the wiring from the brake switch back to the lights themselves. I am at a loss to what could be going on, any help would be very appreciated.
