90 k5 blazer electrical crap
 

i changed the transmission and now i dont have dash lights, headlights, fuel pump, and fuel injectors has this happened to anyone else after a tranny swap.:icon_doh:

Nope... What have you done to try and fix? 1 Possibility is you may have pinched the harness that runs along the back of the trans and caused fuses to blow too? Or maybe forgot to hook up a main ground wire along the firewall. Check all the fuses with a meter. Also make sure 12v going to fuse box.
