77 280Z color wiring diagram

[Captain Obvious]

Wayne, My pleasure! Honestly I'm the one benefiting greatly from this drawing and I'll do whatever I can to make it better. And no hurry on the next rev. Maybe other suggestions will come up.

Either that, or you must be one of my multiple personalities that has escaped and has established himself in PA now.

You'll never tell.

I didn't mean I couldn't find files for the other years, I couldn't find the THREADS for the other years to post Capt's findings to.

That's why I merged the threads to make it easier, especially since the title already had them in one thread.

FWIW

I apologize for the delay - just started a new job and other life happenings derailed my reply with revisions.

Hi Wayne,

Really appreciate your work on this and everyones input. Cant wait to print it on our plotter tomorrow and hang it up in the garage.

Wayne, It looks awesome.

Thanks again for all the great work you've done on this! It's an amazing piece of work!

Almost done with our '78 California 280Z restore; this diagram should help clear up some confusion. My wife learned to drive on this car 35 years ago!

Almost Finished!

Very nice - I like the color and the wheels.

I've turned up a few issues with the 77 color wiring diagram:

a) Hazard Switch Illumination Lamp Missing

Defroster Relay Internal Short

c) Ground Connection Missing

a) Hazard Switch Illumination Lamp Missing - The hazard switch includes an internal illumination lamp, but that lamp did not make it to the color wiring diagram. Here's a snippet from the FSM showing how they represented the bulb:

That works, but I find it a little confusing because of the implication that the connections to the bulb are affected by the ON-OFF switch position (which they are not). So, while simply adding the bulb to the color diagram just like the original FSM would work, I would humbly submit that it would be better represented by something like the below:

Defroster Relay Internal Short - There is an internal shorting connection shown on the defroster relay. Simple fix as shown below:

c) Ground Connection Missing - There is a bunch of items that need a ground connection in order to function, but do not have one. Again, simple fix as shown below:

This diagram is such a lifesaver (or at least a carsaver)! Can we get this post as a sticky?

Captain - Again, thank you for the detailed response for the necessary corrections.

Here's to Revisionn K!

Hi Wayne, Awesome. Thanks for the help!

Out of curiosity while I got you here... There is a device on the dwg called the "Timer Unit Belt Warning". It is located to the left of the fuseblock and is near the new ground you just added. You have all the connections to it listed as US only, but the 77 FSM that I have makes no distinction for that module based on vehicle destination location.

So, is there another document somewhere that lists that module as USA only?

Thanks again!!

I just did the internally regulated alternator modification and as a side benefit of doing that work, I now know the charging systems inside and out. Armed with that dubious knowledge, I discovered a mistake on the 77 color wiring diagram.

Inside the voltage reglulator, some of the components are misplaced:

Not sure it's enough to warrant revision "L" or save it until there's more, but if I didn't write it down, I was going to forget!

This wiring diagram is better than sliced bread. Way better!
