CCC quadrajets work with the ecm and dizzy to adjust itself, and also used the TPS sensor to relay info back to the ecm for the timing advance. running with it just unhooked is not the ideal way to do it. Since the carb is already swapped, i will just assume you have gotten one with an electric choke. Only wiring you need for that is one that has 12v only when the ignition is turned on. Now about the dizzy(distributor), I would recommend a basic vacuum advance model with an HEI cap. hei cap is one with the ignition coil mounted up top. On the models, you just need two wires is i remember correctly, one 12v battery source and the tach signal wire(maybe just a 12v ignition source too on some). Hook up the vacuum canister on the dizzy to a correct port on the intake manifold or carb, you may need a t splitter/fitting if none are open. As for the ecm wiring, i am pretty sure all of it can be cut with a T5 tranny car. The other wiring you will see is for the engine sensors which run through the drivers side harness to the dash. You'll have one for oil pressure and one for water temp(drivers side head i believe). Basically any wairing going up into the passenger side fender/firewall will be obsolete.
Speedos went electric in birds in 86, and in camaros in 90, so thats not an issue.
The oem tach wire will easily read the analog signal from an hei dizzy.
Fan should be mechanical one so no wiring needed there.
Fuel pump is also mechanical so thats an easy one.
O2 sensor(s) are useless without ecm so that wiring is obsolete.
NSS is off the clutch pedal and just ties into the ignition system under the dash.
Reverse lights are off a switch in the side of the trans and wiring should come up from under the car on the drivers side of the trans tunnel.
