~ While I was at the junkyard, I spotted a couple of Vegas that need serious restoration that I wanted to share. He doesn't advertise them and there are several more deeper into his overgrown boneyard along with several Monzas. Sad to see them continue to rot away. :(

~Dodged the hurricane bullet~ Replaced and soldered ALL/EVERY bulb socket in the rear harness and in the front engine bay harness. There was no nice way to clean the socket terminals plus they were 44 years old and I didn't want any surprises.
~ Sorting out the engine wiring harness and replacing the alternator(2 wire) plug with one compatible to the TuffStuff alternator(4pin all same size) terminals. Fun-NOT!
~ Officially mounted the carb and set the air cleaner height, had to trim off an inch from the air cleaner bottom lip so it could sit a little lower.
~ Trimmed the new accelerator cable firewall plug to fit the square hole and discovered it to be too long. I will need to modify the length after we get a bracket to hold the cable and re-attach the crimped end. - More FUN!
~ The braided fuel line is ready to attach but the plumbing is undecided.
~ The exhaust turndowns are in production.
Bad news is that the radio issue is still unsolved so the cluster is still on the bench. I see what they did in the Sunbird and Safari V6, with air...they reshaped the carrier to accomodate the plenum so the standard "huge" Delco radio would fit. Looks as though the RetroSound unit at 300 bucks is the way out of this pickle....Peace

Sounds like you have a cs130d, L goes to small wire for light in dash and S goes to battery positive. P & F not needed.

Paid about 300 usd for my Retrosound Hermosa on Amazon

The original alternator was a Delco-Remy 10si. The car does have the ALT idiot light. The replacement alternator is the chromed 125 AMP Tuff Stuff 8206NA. Their tech. support info differs from your info in that "S" and "F" are used and "L" and "P" are not. They brought my attention to a threaded hole on the back of the alternator and advised to attach a ground strap to it and to ground.
~ Classic Sound radio should be here today, one inch shorter than the Delco. If it doesn't allow the dash cluster to fit and bangs into the Sunbird ductwork, I may have to use a heat gun on it and massage it a bit. We'll see.

~~EDIT- Upon closer inspection, The 74 gt did NOT have the idiot light for the alternator. It had the amp gauge which has been replaced with a 75 volt gauge. Sorry for the confusion.

~Speedo cable is connected down below and insulated with heat shielding sleeve, firewall grommet is at National Parts Depot for 3 bucks.
~ E-fan T-stat - Had to remove the e-fan to mount the sensing bulb for the adjustable thermostat and route the tiny tube between the e-fan and radiator on the drivers side, near where the charcoal cannister used to be. (more wiring-uggh!).
~ Throttle bracket with double return springs is ordered and in transit.
~ Franken-Mod - 03 VW Jetta power distribution block is ordered. It should handle the extra circuits that we will be adding such as the power seats and e-fan. We intend to make the stock single terminal power block into a (-) Negative terminal.
~ Radio issue was solved with a Retro-Sound Laguna 2 with Bluetooth, hands-free telephone, USB, AUX. I am only going to run 2 JBL 6 x 9's in the rear. They are 8ohms each, the radio is rated at 4ohms-25 watts per x 4. I wonder if this means that the 8ohm speakers are only going to get a max of 12.5 watts each resulting in the need for an aux.amplyfier.
~ Hidden powered antenna is to be mounted under the dash where the single front speaker was originally located.

Lately I have been dealing with circuits such as, theft deterrent system..buzzer when key is left in ignition, wired into the dome light circuit.
~ The seat belt interlock circuit which I think may be the mysterious unidentifyable wires under the dash coming off the dash harness towards the center.
~ Neutral safety circuit which I think was jumpered out when the car went from an automatic to a 4 sp.
I have learned that the idle solenoid circuit on a car with air conditioning and a 4 sp. disconnects when the clutch is depressed so that the rpm's will drop to facilitate smoother shifting.
I hope the reverse lights work when we try them out. It's switch is under the car at the shifting linkage of which has new bushings and has been adjusted already.
~ Dealing with seats- the 2 electric leather ones that I repurposed from a Toyota are NOT going to work, I would have had to change the seat belts which I already had restored anyway, so, since I already had the back seat repaired, (perforated black Cosw. material), I will probable have the original Cosw. seats recovered to match the back. Oh, custom of course with a chevy bowtie and the word Vega embroidered into it.
~ I am wondering if even though this car never had rear window defrost, if the harness had the wiring anyway and may be part of the reason I can't identify a couple of the wires.
