Ford 4000

[Troy H]

Hello, I have any early Ford 4000 with the 4
cylinder gas motor in it. Someone has converted it
to 12 volt but the wiring is a mess. I think the
best would be to replace all the wiring. Does anyone
make a complete wiring harness and a diagram to put
it all together?
Thanks, Troy

Depending on the type of conversion, single wire/three wire etc, our hosts
have them.

I usually just make my own. They're not really too complicated.

I would just buy a new harness and get it done with. Search for JMOR's wiring diagrams. They are the best. Email me if you can't fine one.

If you have a 3 wire Delco alternator, post back and we can help you. Takes a bit more wiring than the usual new harness provides.

If your conversion uses a delco 10si alternator you can use this wiring diagram I drew and build your own wiring harness. Works much better than the store bought harness.
