i've colorized another wiring diagram and am now making it available for download. this one was much less of a headache than the '76 diagram, being about 1/3 the size and complexity. download the U.S. 1972 240z here! special thanks to EScanlon for helping me iron out a few problems with it. stay tuned for more diagrams in the future. PS: though there isn't a lot of text on it to search, it IS searchable in a pdf viewer.

Could anyone tell me what this is on a 260z. If you also know how it is wired you rock!

So for the past couple of weeks I have been working on a wiring diagram whenever I have been bored or drunk. So here is the nearly final diagram that I will be putting in my car. larger version http://farm5.static.flickr.com/4057/4439513011_17611f45c7_o.jpg the point was to start new when i install the new dash, get rid of everything possible and use switches, replace glass tubes with and bladed fuses/breakers; since i have yet to find a diagram that does that i decided to make one and share. a couple notes on the components. -designed to work for a 240z, but really anything is possible with this -all gauges are to be assumed autometer unless i find a better/cheaper option, or i decide to use a motorcycle dash and figure things out that way. fuel gauge has 350 and 360ohm resistors ran in parallel. -wiper motor is the honda wiper upgrade, based off of the diagrams that were posted on this forum. switch is low/off/high -gm hei 280z dizzy conversion -euro/jdm rear light blinker mod; via the write up found on this forum -turn signal and indicator lamps (front and rear) are re-wired to work like the kit that was sold here and the one at MSA - all switches are ground switches, unless not really possible. everything that was operated by or from a Datsun stock component has been removed and replaced with a switch or button. -e-Fan is a Pontiac V6 Fiero fan, and the manual switch can be replaced with a temp switch. -alternator is the CS144/280zx internally regulated alt upgrade, write up found on this hybridz === this essentially my first attempt at wiring a car. Any input would be greatly appreciate, and any ideas would be awesome as well. The only thing that I have yet to draw in is the stereo, if you could call it that; essentially it would be 3.5mm headphone jack to speakers. I dont want the radio, or cd player from a dash unit just the AUX in. I think I will need an amp, or some type of signal booster, so that the two speakers will have some umph to em. I have yet to really research this, but once I find a diagram that will work I will add it in. once the diagram is complete it will have routing plans so you can have a coveted "invisible harness", wire gauge and length; and total cost needed for the entire car. Or, if anything, to be used with a painless or EZ-Wiring kit.

I'm working on a color version of the 1972, and i'm having some problems sorting out the colors of some of the exterior light wires. Mainly, the white/black and white/red wires that go from the hazard light switch to the brake lights. when coming from the hazard switch, the white/black goes through a connector of some kind, comes out the other side as white/red, and in some unmarked spot between that and the light, turns green/black. it's the same sort of thing with the white/black coming from the hazards. can anyone tell me what the actual colors of these are? also, what is the connector they go through that's depicted in the diagram as a bar? please see the attached image for reference. EDIT: can anyone tell me why some of the wire lines are dashed?
