Datsun 510 Wiring Diagram

This wiring diagram is copyright DAMB productions. A large laminated copy can be ordered from Kelvin Dietz (see below).

Did you ever notice that 510 wiring isn’t particularly self-explanatorily? A little strange, to say the least? And then to top it all off, when you try to troubleshoot some of this wiring, the only clue you have to where all those bits of copper and plastic go is a 8 x11 drawing that all runs together in a spiderweb of black lines that have been smeared into illegibility from too much use, making it all but impossible to use even if you did have a working concept of automotive wiring which at this point you’re wondering if Datsun engineers did and you KNOW that Datsun draftsmen didn’t!!!.

Well, you get the picture. Or not, as the case may be.

DAMB Productions to the rescue. With a little encouragement from my Internet friends, I decided to create the ultimate Datsun 510 wiring diagram. I had a graphics arts friend color in a 11×17 enlargement of the diagrma and after about 20 revisions we had this multicolor version of the original.

During this process, I was tearing my harness apart for another project, so I could compare actual wires to paper wires. And I found a few discrepancies which I fixed on the diagram. I also took the suggestion of a friend to include connector pinouts. A great idea, considering some of those white wires don’t look all that white anymore. I also added connectors where the original diagram doesn’t show any or shows the wrong ones.

Other features include optional wiring for an internally regulated alternator, firing order, and legible switch diagrams. A few lines have also been re-routed to show them going through actual connectors. Finally, the diagram’s laminated so you don’t have to worry about smearing or tearing it. Those dirty fingerprints wipe right off.

This diagram is explicitly for a 1971 manual transmission 510 Sedan. From what I’ve seen it will work on most of the late model wagons or sedans. (’70 –’73) There are various relays, lights and switches that might not be there, but the majority of the diagram is accurate for these cars as well.

I’ve gotten good reviews for this product from everyone who’s seen it and I’m happy to make it available at a reasonable price to all 510 enthusiasts. $12 each or $40 for four. Why not buy four. They make great placemats!

    The text is signed Kelvin, but the fine print at the bottom of the page says ‘this was written by gsmith’. Did you get Kelvin’s permission to post a full size version of the diagram for everyone to download for free? Would be good to clarify this point, because a quick reading does not notice the fine print and assumes that this full size download is endorsed by Kelvin.
