The air cleaner ***** are a tough find. Think junk yard from a cross fire engine (not an everyday find in a jy either). Also take a look at this thread on the History and Restoration board https://www.thirdgen.org/forums/hist...sfire-air.html
I suggest you visit e-bay and pick up a 1982 Camaro Service manual. There are 7 listed tonight ranging in price from $18 - $24. A new one is also shown for $70. Note that the colored circuit diagrams at the back of the manual do not document the ECM connections for the Cross Fire engine. They only show the connections for a V8 carb engine and the V6. There are several pages showing the complete wiring diagram, but this diagram does not document the connector numbers as the colored diagrams do. You might also pick up the TBI service manual, as they give some tips hon how to tune up and balance the TBIs so you get equal fuel flow to each side of the engine.
Running with out the EGR and the air tubes may cause you some grief as the ECM may sense values out of the normal range and run the engine rich or lean. The EGR is no big deal, but your engine block is not equipped to handle the air tubes, nor is your exhaust. This will cause the oxygen sensor to some times report out of range conditions to the ECM, which will try to correct them.
One item you will need for input is the Vehicle Speed Sensor, which in the 82 cars is located on the circuit board that is part of the dash. I think it looks at the RPM output from the distributor and converts the signal to send it to the ECM.
Other under dash circuits connecting to the ECM are to a 10 amp fuse and to the ALCL connector. You will need this connector to get the Error codes from the ECM. There are about 80 pages of CFI trouble shooting charts, based on the error Codes for the CFI engine. I would consider this a must have for your project.
I hope you have a return fuel line accounted for in your project. The TBI units require on to function properly.
How do you intend to handle air injection into the top of the air cleaner when you drop the hammer and the ECM see a WOT condition? On the 82 cars this was achieved by opening the hood louvers and pumping air directly into the top of the air cleaner. Before you painted the air cleaner, did you notice the gasket ring around the top of the housing? There was a gasket on the underside of the hood that sealed the top opening from the engine compartment. The when the louvers opened, the air was forced into the air cleaner. Pin 7 on the black connector ran to the control relay for the hold louver solenoid. A WOT condition would energize this output to close the relay which would power the louver solenoid to open.
I took at look at the schematics and figured out a few things. There 4 3 fuses in the fuse block that you will need to duplicate and one direct connection to the Battery + terminal.
On the battery terminal there is a fusible link, Wire # 2, 16 AWG. This connects to wire #340, Orange that provides power to the ECM memory. This should be a single connector with an orange wire that would stretch on the inside of the wheel well to the battery in the 82 car. The 10 amp ECM fuse is only hot when the ignition switch in in START of RUN. This circuit is Pink/BK and powers all the sensors, as well as two direct connections to the ECM. Its wire number is 439 in my first diagram. The other two fuses are both 3 amp,, only powered with the ignition in START or RUN and. One fuse powers TBI 1, is red and its wire number is 480. The second fuse powers TBI 2, is white and its wire number is 481. Finally the Gage Fuse, again only powered when the ignition is in START or RUN powers the VSS mentioned above. I suppose you could just power the VSS off of wire 439.
The attache pdf is an attempt to scan the CFI wiring diagram from the service manual. I zoomed in to only show the ECM, both ECM connectors and also the under dash connector that was located just to the left of the ECM in the 82 car. I suspect all the fused circuits and the VSS, ALCL connector and the check engine light were connected to the ECM via this connector. As you can see, it is not very legible.
I will post a few more questions for you to think about as you proceed with your project.
