I just wanted to put it out there that I finally finished making single page wiring diagrams for 1972-1977. If you remember, these were in multiple pages which made them a pain.

Oh, and I made them in different versions too. I'd be curious if you have a preference.

Also, let me know if you spot any mistakes (I'm only human) or have any other criticisms.

Cheers

Groovy. I can't tell you how many times I've used your site as a reference over the years.

Thanks for taking the time to put all of these together.

That's great! Just saw some of the changes the other day for the first time. Got pretty excited when I saw there had been some updates.
You and Steve83 have been the go-to diagrams for years now. Glad to see them getting even better.

Definitely thanks for taking the time.

Thank you! Should these say 1975-1977 instead of 73-74?

Good work. They look pretty good. A couple things could be added though. Breakerless Ignition was used in some areas in '74 with a black grommet module. '75 had the Solid State Ignition with green module. '76 and '77 used Duraspark with blue module. All 3 had different wiring to the module and distributor. See my attachment.

'74 should have a PRNDL light and horn relay like '75-'77.

'73-'77 should have the neutral safety/reverse switch and manual trans jumper/reverse switch wires. I don't know if these were ever shown in the Ford diagrams but it would help.

Okay, now you've given me some homework to do. I can make the corrections easy enough. For the ignition systems, I think I should make up some examples and run them past you to see if I get them right.

I'll get you some pics of the factory diagrams for the ignition.
