i need help on my 72 blazer

I just got my 72 blazer back from 2 years in the body shop. I had alot of extensive body work done (cutting out the rot and welding in new metal) Anyways, i had the cab removed. When they put the cab back on, they had to re-wire everything back up. Now none of my lights or turn signals work. I checked the fuses and they are fine. Now what do i need to check??? Any help would be appreciated. I bought it and it went staight to the body shop. I'm jonesen for that first ride!!!!!!!!!!!!
