I am having trouble figuring out your pictures;
Are all four pictures the same harness?
It looks like three of them have the same headlight sockets...



That is for sure the front light harness.

The lighting harness does Not look correct for 1973. It looks more like 70-early 72. Why? The front parking/ signal connector is for the older style set up with metal housings.
73 had a basic bulb socket on the harness that the 1157 went in, and it simply went in back of housing and quick twist, like a tail light bulb.

All those harness are underwood. GM didn't use that plastic wire cover under dash....it was wrapped..

that corrugated cover wasn’t used by GM till well after the early 70’s cars were built;
I believe that the under dash looms were wrapped with a type of tape that lacked adhesive, and the under hood stuff was wrapped with a tape in spots, and used a vinyl sleeve in other spots.

Since the corrugated cover is there, I am guessing you would have to remove it to find the side marker lamp wires.

Pictures of the connectors close up on the harnesses may help ID correctly. The 194 side marker bulb connector is usually white.

Get through the weekend, & can do some checking originals for you George. Have many stapled up paper sacks of original engine & front light harnesses. Each sack is tagged as to what the harnesses came out of.

On the plastic convolute tube covering, know my '73 BG project cars original engine harness has that covering. It's an off gray. Years back, had a smoking deal on new wiring harnesses from American Autowire & I ordered several engine harnesses for '73 T/A's w/o air conditioning. Their repro engine harness is spot on & has the correct covering too.
