I noticed a crossed wire in the Illumination circuit for the Water temperature/Oil pressure gauge a while back. Didnt think it was worth mentioning, but if there is a revision, then it can be added.

This colour wiring diagram is truly awsome. Thanks for all the effort Wayne.

I printed it on an extended A1 format and it hangs on the wall of my garage. So much better than the FSM.

Good eye!!

Captain & Chas... I've made the edits, attached is Revision 'L'.

Thank you both for the kind words and the skillful quality control![ATTACH=CONFIG]73723[/ATTACH]

Here's the latest. It's Revision "M". It includes the two changes mentioned above (voltage regulator and illumination light in the Temp/Oil gauge):

Wayne had asked for me to take a look at it and upload it if I got the chance. Never tried to attach a pdf before, so let's hope this works right!!

Thanks again Wayne!!

Uploaded newest version - M

There were a couple small issues with rev. "L", so Revision "M" has just been uploaded. It's awesome.

Excellent work. Thanks for the quick update.

Updated the file to version M.  @wal280z is now the file owner so he can update the next time without needing to wait for me.  ?

 

Maybe Mike can rename this thread “77 280Z colour wiring diagram” to avoid confusion with other years.

And for anyone getting ready to print out a big copy of revision "M" to hang on their garage wall.... Don't do that right now.

There have been some recently discovered issues in Rev "M" and I believe there will be a Revision "N" coming out soon to fix those issues.

So if you can hold off for a little bit, do so!

No problem. I edited the topic and updated the link to the file download in your first message.  I also added a link to this thread from the download details.  Thanks for supporting the file and keeping it updated!

Now that all the (known) issues have been addressed and edited, I have updated Revision N to the download section.

Changes to Revision N

1) Fixed wire colors going to oil pressure sender and tachometer resistor.
2) Changed fusible link positions to reflect correct positions on vehicle.
3) Changed internal picture of alternator.
