Headlights aren't working after motor swap

[chevy_cr250]

I have a 1988 Chevrolet k5 blazer it had a rod knock so I pulled the motor and found out it was a 307 out of a 69 Camaro bored .30 over so I sold that and got a 350 out of an 86 Chevy truck, cleaned it up put it in everything is good and working good except now my headlights/daylights and interior lights don't work they did before the swap. I replaced the switch and the 2-30amp circuit breakers, fusible link and cleaned up all the grounds I could find and nothing. My turn signals and hazards work fine but no dash no dome no headlights/daylights. I only have 1 ground strap to the firewall from the passenger head and then next to that is 2 more grounds that come out of the harness, I have 0 volts reading on my horn/dm tl/ctsy and ecm fuses.

Thanks for the help and info
