Sorry that I can't help you, but welcome to the forum. Have you tried looking at Messick's to see if they have anything that could help?
I would expect a diagram inside the box for $360 (typical Dealer price).
There was nothing onsite.
I paid $120 at TractorPartsInc
I found out that my Ford 545C had a D5NN10300D in it, when I removed it.
The E7NN10B376BB was recommend by all the research I did prior to ordering it.
By fabricating a belt tension bracket, I was able to install it but then became stumped by the wiring as the Alternator is not marked.
Apparently the new alternator has a regulator in it, so all I have to do is hook up the Battery wire and one to the guage.
