Identifying EFI parts
I'm putting an '87 Mustang fuel injection onto my '84 mustang 302 which I have in my '51 truck. I'm in the process of sorting out the wire harness and there is 3 vacumn controls I don't know what they are for. I know where they plug into the harness. Here's a pic:
Two of them are attached to a plate and the other one is inline with the vacumn hose. Also do you guys know what is supposed to fit in the big hole at the back of the lower intake.

The big hole in the back of the lower intake is where a screen breather, then a PCV valve sit on top of it, the screen part may not be available at the auto supply stores, dealership for sure. Don't try to get by without the screen, you will wonder where all the oil is going. I sold my stang so I can't help with the hose situation, although I think it is strictly emissions related.

The part on the right is the canister purge valve that goes between the carbon can and a port on the intake manifold or throttle body. The two solenoids on the left look like the TAD and TAB solenoids that control the air injection valves in the smog pump system.

I have the rear air ports on my heads blocked off, so I won't need the 2 solenoids since their just emissions right?. Is the canister purge valve required? I have the screen and had a PCV valve on a short hose but it wasn't attached to anything. Now I know where it goes. Now the valve covers have I'm using have caps on both covers. So will I need to cap one closed since the PCV valve is in the intake manifold? Thanks
