I have a wiring diagram for 1973 in electronic format but it's too large an attachment (500K+) to post here. If you send me a PM with your email address or an email through the Forum (click on my user name and you'll see both options there), I will forward it to you.
Don't post your email onto the open forum unless you like getting spam. Spammers use special search programs to locate hypertext (like email addresses) in open webpages and then use and/or sell that information. For instance, if the search parametres were "Corvette, hypertext" they will be taken to every Forum post which has an email address in it. Don't give spammers a window of opportunity by posting your email address.
Spammers call these types of programs "targeted searches" and claim they're simply locating customers who might be interested in their products. Spam, by definition, is unsolicited email, so if they're sending me email without my knowledge or consent, they're spammers.
