So most likely if I don't have a highly optioned car some of the plugs were not used? Ryan
Nope, that pink molex plug is unique to the 1972.
Correct, this is a 72. The only things I have on the board is the flasher, a circuit breaker (I think) and a clear small box marked D0AB-13150-B2. Would like to know which plugs go where and which ones are not used.
Here's how I figure out what components are where and what plug is used....
Your D0AB-13150-B2 returns a Google search as a key warning buzzer. All of those components on that plate have part numbers stamped on them, and there are a couple screws that come up from the inside of the glove box so you can drop it down to make life easier.

Page 2 of the 72 full wiring diagram has a component locator index, the key warning buzzer is in grid
F53.
The diagram is arranged with i.d. numbers across the top to designate vertical columns and letters on the side to designate horizontal rows.
Scroll down to the page (4) where the 50s start. If you trace down from 53 and across from F, you'll find the area with the key warning buzzer depicted, along with it's wiring traces.
C-89 designates the connector that plugs directly into the buzzer. Follow the leads back and you will see 158A/BK-PK (H) and 159A/R-PK
158A is the circuit designator and not something you'd use here. BK-PK(H) is the wire color ID. The layout is always (base wire color)-(stripe color)(stripe line type) BK is black wire. PK is pink and (H) designates a hashed stripe (dashes is you prefer). So, wire 158A is Black wire w/pink hashes. R-PK is red with a solid pink stripe. It looks like it's the connector hiding under the square red plug.
Another stripe line type you'll see is (D) for dots.
Do this for the rest of the bit on that plate and let's see what you have left
