Re: name this part,tbi 350

Firts pic with the fuse should be your fuse for the ECM. Not sure about the second pic maybe with the Vehicle speed sensor? Third pic is your fuel pump relay. I also installed a TBI system on my 72 Blazer. I used a custom harness it got rid of the junk you don't need. Good luck I'll help where I can
