Pic 1 - looks correct if the electrical connectors are at 6 o'clock on the front.
Pic 2 - left tube pointed up and forward looks like air tube to cat. Other tube ?
Pic 3 - looks like air tube to air tube that run to cat.
Pic 4 - looks like crossover air tube from left to right banks.
Pic 5 - looks like vacuum hose that hooks up to underside of TB, goes to drivers side to
vacuum hose to charcoal cannister control valvc.
Pic 6 - No idea
Pic 7 - No idea
Pic 8 - Looks like filter for air diverter, goes in front of engine with Pic 4
Pic 9 - No idea
Pic 10 - Looks like filter capacitor, possibly tach filter
Pic 11 - Hot water tube for heater supply hose
Pic 12 - Same as 11
Pic 13 - Looks like water hose to bottom of TB.
Should get you in the ballpark, this is all from memory, I can check FSM tomorrow and see.

6 and 7 are the PCV lines.
PCV valve goes in LH rocker cover grommett ( front ) with hose to fitting on intake in behind # 5 injector.
Solid line goes RH side from tube on throttle body to gromment in RH rocker cover ; rear
All the AIR system can be deleted to cleanup the engine bay.Remove everything and just cap off the two fittings on the exh manifolds
11 / 12 is the coolant air bleed from rear of intake.Can just block off
Tach filter goes on top bellhousing bolt LH side , by oil switch; one wire to plug on loom , other to dist if I remember right
You are going to take pics NEXT time aren"t you

The AIR system are all the big pipes from the air pump.
Remove everything , tuck the spare wires back into the loom somewhere.
Cap off where the hose go to the air pipes on exh manifolds. Fitting shown in pic 2.
The smaller lines under the intake supply to the EGR solenoid then to the EGR valve.
If you don't want EGR to work ,only need vac line to fuel reg and line that goes into cable loom behind dist that operate the A/c functions.

Haha, it does indeed.
I have the EGR blocked and the air lines removed/blocked off, with no issues. The connection to the cat is a tube coming out the side of the cat. remove all the hard lines and block off the hose leading into the cat. Plumbing caps work for the exhaust manifolds.

The connection for the cat runs underneath of the car along the passenger side and thats the line you see in front of the passenger side header. Its secured to the fender well down low by the exhaust. Its kinda hard to reach.
IMO the engine looks a lot better without all the AIR hookups, especially with headers on it now

EGR is to keep your car out of detonation and gives better gas mileage.On a scale of 1 to 10 you can only hear 1.Your knock sensor should help with detonation but will retard your timing.
