That appears to be all of it. If all your equipment works, you didn't lobotomize it too much.

Did you also remove the solenoid from the passenger's side of the intake manifold? You don't have to take the pressure switch off the trans unless it is leaking.

Looks like it to me. I used the 10 gauge pink wire for my HEI installations on both my 72's. There was an idle solenoid and a vacuum switch located on the intake. Getting rid of all that really cleaned up the motor. I don't recall having those holes in the firewall though...
