My 1981 633CSI's tail and brake lighs have stopped working. They keep blowing fuses about a min after I replace the fuse, it blows. Obviously there is something shorting it out. Any ideas of where to check first.undefined

Not really sure, but here's a few things I would suggest:
Check you connections. Make sure they are clean and in proper order. Check your rear wiring harness for signs of damage. It sounds like you have a bad ground or a wire that might be frayed and shorting out.
Make sure you are using the proper size fuse (I'm sure you probably are, but just trying to cover all the bases).

My mechanic had to replace the whole wiring harness. I t was in terrible shape, so he said. The lights work fine now.
