I'm an electrical engineer working in aerospace, and I make wiring diagrams and harness drawings for a living. From an overall perspective, this is a fantastically well done, easy to follow, easy to troubleshoot harness. It's exactly what I would expect from the era! I really appreciate that you took the time to walk through it, as it's something on my long, long list of things to do with my '77 build. I have this grandiose plan to rewire the entire truck to my own spec and use D38999 Mil-spec connectors as passthroughs in/out of the cab. Mind you, I haven't decided on an engine swap option yet so things will assuredly get more complicated in the future, I'm sure!
They are great for what they are designed for. It's when a bunch of stuff gets added that problems typically start. Thanks. I have similar plans far off in the future haha.
@@spacemonkey339 The 73 is much simpler. Nicoclub has all the Datsun wiring diagrams. Here is the 73 www.nicoclub.com/service-manual?fsm=620%2F620_1973_Datsun_Truck_Wiring_Diagram_MT.pdf
Great video! Exactly what I needed! Thank you very much, now only to apply my newly acquired knowledge and hope I can find my electrical gremlins haha
You are welcome. Glad to help, good luck in your battle

Just bought a 1976 620, this helped out a lot. Great work!
Thanks. Glad it helped.
Never thought it would’ve been so much wiring 😂
Earlier years of 620 were more simple.
And that was without the California BS lol
This will help when I start my wiring process although mine is a 73 not sure how different the harness is on the older ones
