a lot of the old Cobras were wired by people who knew a "little bit" about wiring a car.
Most of the older Cobras I have worked on have a lot of wiring issue.
What type of fuel panel does you have? Fans, electric fuel pump, heater, wiper, push button start, etc.
Do you want to use what you have or can you afford to buy a new harness and start over? Harness should cost $300 to $500.
I draw my own diagrams for the components that I want to install. If you tell me what you have or want I could draw one for you. Something I like doing. It's more fun than watching TV.
I do have a lot of diagrams saved into a computer folder but not a full dawning for a Cobra.
Please feel free to email me if I can help.
