Chassis wiring diagram

Post by TimCarlson92 » Sat Oct 21, 2023 8:56 am

Does anyone have a wiring diagram for where the wires are supposed to be on a 24 coupe? I'd like to restore their placement properly. I have a great wiring diagram for which wires go to which part etc, but am sturggling to find a diagram of where they go on the vehicle itself.
Thanks for the help!

This is the one for '21-'25 chassis with starter, generator and storage battery. Only difference is the high cowl wiring loom to the terminal block on the firewall has the switch loom hole above the terminal block.

Do you have the Ford service manual? That’s a really good resource of close up pictures of the engine compartment and a way to identify engine parts and the wiring that goes to them.

Once you identify the engine components then you can install the individual wiring harnesses to the engine and the firewall. Using the parts catalogs for parts identification is a great help too.

Wiring a T is pretty straight forward and you can do it. Don’t take off all the old wiring all at once but do “one harness at a time” and using the wiring diagram and the old wiring as a guide. Take your time and remember it’s not rocket science. You can do it.

I just ordered one this morning. I thought to myself, these guys are going to get annoyed with me, I better just get the manual lol! I didn't know it was that comprehensive.

Hi again Tim! We all learn eventually that pictures say a thousand words! That’s how most of us learn about anything mechanical related. I’m not the smartest guy in the world but pictures sure help me.
Good luck!

I didn't know it was that comprehensive.

During the age of the Model T there were many, many publications to show how to keep a Model T alive and running.

All the major motor journals, from the sale of the first Model T to the Introduction of the Model A, presented to the readers Q and A about the "T".

You had the Ford factory publications, and the likes of Page, Dyke, etal giving service information.
