BIT OFF MORE THEN i CAN CHEW

[400/6/PAC]

My 73 had a lot of burnt wires at the fuse box, most of the wires had been pulled out of the car when I got it.
Instead of buying a painless or trying to find new under dash and light wireing harness my dumb a$$ decided to rewire the intire car myself.
I managed to get every thing working ( except a ground problem or misswire at the tail lights ) but I dont know any amp draws.
What size main fuse should I use going to the new fuse box, how many amps do these componants use.
a/c, headlights, taillights, blinkers, wiper motor, blower motor,
Any help or advise would be appreciated.
Thanks
Oh and feel free to go ahead and
