Help me identify these plugs New Ones
I sent my upper aluminum tpi stuff to be polished. Between pulling them, shipping them and fininally reinstalling them it's been 4 months. I can't remember or find where they go. I also have 2 plugs the previous owner had tapped together. i don't see anyplace for them.

Passenger side of engine.


Drivers side.

Vac line looks like it goes into the bottom port on the TB.

The other end of the vac line in question goes to this canister on the front drivers side.

Just a money shot. I have the polished aluminum valve cover to install still.
Any help would be great. Can't wait to get it running again and get it dyno tuned now that I have all the mods done.

Re: Help me remember/intentify these plugs
I got all the above figured out but I now pulled a vac line lose moving the coil wire to where it belongs.
I think I have an idea where it goes but it dosent look like it will fit. New picture what is this? It is behind the coil on passenger side firewall.



First one is wires pluged then wires unplugged and then a better shot of the vac line hook up?

Thats for your EGR. The part of it your showing is a vent for the electrical vac switch.
Someone mounted the coil on the firewall but all that is supposed to be on the pass rear 2 bolts of the intake.
