I tore this car apart 15 years ago and I don’t remember what the wires are for. Coming out of the wire block. I understand all the wires for the head lights,horn ext. it’s the ignition side I’m sort of lost. The two red wires I know go to a power source. I have a light brown 12 gage and a orange 12 gage what are they for? I have a brown 14 gage wire is that the one that goes to the starter to activate it? Two light green 14 gage coming out of one port. A dark green, light brown, dark brown, light blue 14gage I believe are for sensors . I bought a wire diagram but my wires are different must be pre 80. The car is a 80 Monte Carlo

Purple 12ga goes to the Starter. Green 14ga is the Horn. Red 12ga coming in from the Starter or the Battery to power stuff on the inside of the car.

I wiped the 12gage wire with grease and wax remover it sort of resembles purple. How about the light tan colored 12 gage air conditioner maybe?

It could be pink or orange. These wires don’t resemble the color chart that I recall or I’m getting color blind as I get older lol…

All A/C wires come from the other side of the firewall.
Using GM circuit numbers on the ones I can see where they come from on the connector.
2 - to fuseable link and starter battery cable.
3 - To HEI 12+.
5 - To Starter Solenoid.
25 - To Field wire on alternator.
Others:
Dark green - Temperature switch/sending unit.
Tan - Oil Pressure switch/sending unit.
Dark green w/white stripe - Oil pressure switch.
Brown - Oil pressure switch for choke heater.
Optional
Light green and light blue - To TCC Vacuum switch
Light blue - To TCC Solenoid.
Brown or white - To tachometer filter.

I saved this diagram years ago, it will help you greatly.

I have a suggestion. It looks like you have a bunch of cut wires.
Instead of splicing them, go to wirebarn.com and buy new GXL wire in the correct AWG and colors. You can get small coils. I think they sell 10' pieces. I did this to both of my cars. This way you have all new fresh wire. You can buy the Packard terminals that go on the ends of the wire into the bulkhead connector from texasindustrialelectric.com. Theyre not expensive. You'll need Packard 56 and 59 but I dont remember how many of each I used.
Just a thought.
