I just received a Color Wiring Diagram from Prospero's Garage (purchased on eBay). I have noticed these for a while and thought that it might be cheap or incomplete, so with my Z paint finished and re-assembly in progress I went ahead and bought one. I have to say that I am very impressed - so far. Have any of you guys (and gals) purchased one?

He has a website: http://www.colorwiringdiagrams.com/

I am not promoting - just sharing some information on a good find .

I will be sure and post any problems if I find any....

Yes, I picked up one when I restored my 240Z. I was impressed with the quality of it.

It was of some help when we reassembled the car, but for the most part the Z had pretty much plug-n-play wiring. Good reference to have though.

I have one for my 240z and really liked it. I always had trouble reading the black and white ones in the back of the manuals. This was easy to follow and really helped when I was working on the wiring harness.

I just received the "Diagram Datsun Z2 (72?) - 240Z" and within minutes of looking at it in depth, I've found numerous mistakes. For example, the battery positive has no connection to anything other than the starter, the horn is labeled as "passing" and is apparently connected to the windshield wipers, the hand brake warning light gets power from nowhere, The high and low beam switch is labeled as "dimmer," there is no high beam bulb shown in the speedometer, and the high beam wire, right headlight power and instrument dimmer wiring are all shown connected together. There may be more issues, but this is what has jumped out at me so far. Furthermore, switches are all shown only as blocks with no internal connections, making it impossible to trace wiring through the switch.

All of this severely limits the usefulness of this diagram for any kind of troubleshooting and the convenience factor is nearly eliminated because you still need to have the FSM schematic on hand. I guess if all you want to do is follow a wire from point A to B, it's somewhat useful. But forget about trying to understand how the circuit works. It's only going to confuse the heck out of you, especially if you're an electrical novice.

Great idea, but bad execution.
