Exactly what is the problem you are running into? BTW did you hook up your fuel warning lamp hazzard switch ect? I'm trying to figure out if i am going to.

Thanks everybody ! those autozone diagrams are so much easier to find your way around with. !!!

so what does the green white wire do then?

Okay after endlessly searching threw my wiring diagram I have one question that I need answered. It’s the only question I have left about my dash(i think). What does the red blue wire that connects to the light-bulb on my dash gauges do? Is it a ground? Does it need power? What do I do with it as far as hooking it up. On my new harness I have a wire for instrument lights however that runs to the old position of the green white wire. What do I do ?? I’m very confused at this point help ! stock gauges btw.

so got some more stuff done I hope that this is help to sombody at some point Front End of Chassis Headlight Right Head Wire Color Action Red Power from fuse box/ breaks off and runs into speedo Red White to speedo red white then to combo switch high beams 15 Red Black To combo switch low beam 16 Connections are as follows Red white light green then to Speedo Red red 01 headlight power red black Red black tan Headlight left Head Wire Color Action Red yellow power from fuse box Red White to Speedo red white then to combo switch high beams 15 Red Black To combo switch low beam 16 Connections are as follows Red white light green then to Speedo Red red 01 headlight power red black Red black tan *****note headlights wire run together Wiper Motor Wire Color Action Yellow P on amp assy Int Wiper Blue Red to blue white to yellow green to combo Switch Wiper 2 Black Ground Yellow Green to combo switch wiper 2 Yellow Black to combo switch wiper L Blue yellow to wiper H on combo switch Connections are as follows Blue red wiper motor power Now time for a nice little write-up on the wiper From http://www.atlanticz.ca/zclub/techtips/wipermotor/index.htm The Z harness, as I wired it, which I don't fully understand: 6 prong harness: -1- -2- -3- -4- -5- -6- 1: 12v, blue/red. 2: Ground, black. 3: No idea, maybe allows for proper stop/set of wipers 4: No idea, maybe allows for stop/set, seemed to read fluctuating voltage when engaged. 5: High speed, either blue or blue/yellow.

Bob_H Great looking car! let us know how the wiring goes! Hopefully Sparky will let me post his EZwiring Writeup about the ignition switch and various other control switches!

A good alternitive to the c02 would be an abc type extingusher. It will put the fire out however it has an advantage over the c02 as it wont displace as much o2. helpful when you are in the garage.

280Z-75 thanks i have been workin off that diagram tho. On a side note this morning when i got home from work i figured id strip some more of the wire out of the Z, I didn't pay attention and sliced my pinky and ring finger open! so after a number of stitch's 6 in the pinky 4 in the ring finger to be exact i figure i better get a move on this harness 'cuse the car is starting to bite back!

Ok here it is my ezwiring 1975 280z wiring guide. It is currently incomplete and I still have a few parts to workout. They are 1) How to wire up reverse lights 2) Where to source the power for my tail lights (use third break light power?) 3) What powers all my gauge's? this issue stems from the fact that according to my diagram i have to wires running into the light bulbs within the gauge's, a green white and a red blue. However the ez only shows 1 wire for this light . Thinking the the red blue runs threw my dash dimmer and alters the current flow to dim my lights? and how to hook up my dash dimmer? 4)What circuit I want to use to power my ignition box (msd unit). anyway this is what I have worked out thus far. It shows what color the wires are and what they do and how to connect them to your Ez harness . I hope it serves as a good starting point for others. I know that others have broken down other sections of their Z harness and how it mates to the EZ please post and help out! **note connections are as follows describes the original wire color first then the EZ harness color after Rear Section Left Side Right Side Lamp Wire Color Action Black Yellow Stop Red Black Reverse Green White Tail Green Red Turn Black Ground Connections are as follows Green White Brown Green Red Yellow Red Black Black Yellow Stop switch Right Side Right Side Lamp Wire Color Action Black Yellow Stop Red Black Reverse Green White Tail Green Black Turn Black Ground Connections are as follows Green White Brown Green Black Green Red Black Black Yellow Stop switch ***Note Stop Switch connects to fuse panel License Plate Wire Color Action Green White power Connections are as follows Green White Brown To Lower Chassis Wire Color Action Yellow To Fuel Gauge Yellow Blue To fuel warning lamp Green Blue Fuel Pump Power Connections are as follows Yellow Pink Green blue Dome Light Wire Color Action Red White Into Drivers Seat Switch To Assorted Seat Switch To fuse Box to ignition interlock Black Red Door Switch Right Hand to C-1 Black Ground Connections are as follows Red White White Brown to door jam switches Black Ground Dash Dash General Wire Color Action Red blue To control Panel illumination Lamp Runs to Radio and hazard Switch Green White To Light wiper washer combo switch Runs also to glove box lamp Front Section of Z to T/S park lamps Black Ground Connections are as follows Red blue Green White Brown Amp Meter See Notes in book for more Install information Wire Color Action Green To Speedo White To Shunt Split into two sections Fusible Link to starter Terminal with B wire From Battery Pos Voltage Regulator Connections are as follows White- Route the 10 gauge solenoid pwr = red wire from the fuse panel to the amp meter and then from the other post of the amp meter out to your pos bat source.

Mycarispurty I am currently also re-wiring my z with an ezwire kit. As far as inteiror items I plan to keep my dome light. Obviously my gauges however beyond that I really dont think their are any other items that need electrical hookups. I just got my kit in the other day so i havent really torn into it well however I did notice that the lines for the dash seemed very short. so I was planning on using my existing Z dash harness and connectors and just patching it into the ez harness. this would allow me to place the harness in its stock location and use existing connectors to make my connections. I havent gone threw my harness very well im still trying to get it nice and sorted out however have you found the wire for the brake lights? I found the thrid brake light wire but not my left or right brake light lines.

Dragonfly thanks for the tips. (I had forgot all about the gromets) Im hoping that my install turns out as nice ,and easy as they make it out to be on the website. As long as I take the proper steps it should. I purchased this kit http://www.ezwiring.com/twentyone.htm It should fit my needs and give me a bit of room to grow. It also elimante many pita aspects of the job.

perfect timming on this thread for me. Im about to install a Ezwiring Harness and have to re run all my wires to my fuel pump and so on. So minus the rope method any other tips? all my mechanical is up in place and Id rather not mess with it as it works fine (right now) Pass on the knowlage please !

This is a wonderful topic that really addresses detail within work and craftsmenship. Can anybody suggest some reading that deals with the subject matter at hand? Ie preping good race motors or 70's F1 engine building?

I personally like the look of the "F1 style" mirrors. sleek and subtle yet give a nice race car inspired look.I think they will look great once I get around to it/them.

75 280Z Purchased in 2002 drove till late 04 then started sbc conversion. It runs now but ive got a list of things to redo. All I can say is do things right the first time, and dont let your "friend" work on your car while you are out of state/country. Sorry didnt mean to rant.

congrats darius. My car runs, and then its apart,then it runs and then its apart. Post some VIDZ!!! I cant wait to see your Z in action again.

Is their currently a timeframe for the next test session. If its later this year I hope to have a diffuser on my car ( I just love the look) and I also plan to incorprate many other aero mods that have been tested. However im just starting on these mods so ill need time. I'm trying to decied if i want a gt40/NSX style vented hood. The reason im still uncertian about such a mod is that it consumes a bit of my engine bay. Currently I have the space but I've got this urge to slap a turbo on the small block. I'm trying to put that urge to rest. I guess what im saying is id like to help out and Im stationed in South Carolina so im fairly close.

Stunning!!! I just cant describe it, truly a work of art.

Thanks for the knowalge ! That answered my questions, now I gotta figure out some way to apply this information..

TitaniumZ Good job on the Z! Thank you for allowing wind tunnel tests to be run on it and sharing the information. Your Z is highly innovative, nice ride man! While I’m at it thanks to everybody who was involved! Hope I didn’t get to far off track. Got a few questions as I am still trying to digest all of this wonderful information. With the side vents being feed from the “holes†in place of the battery the air transitions through the ducting, and out to the lower pressure outside of the car. As underneath the hood is a high pressure area and the difference in pressure causes a “vacuum†effect thus sucking the air out the side vents correct? However as you have the inspection cover vents directly above these that allow air to exist and thus relive pressure (or at decrease it locally) isn’t the efficiency of the side vents decreased? Or is their something I am not seeing? Or is their relationship mutually beneficial? Also have you seen a difference in running temperatures since all of the aero mods if so how much? Once again thank you to all involved I hope in someway someday I can contribute something as profound as this to the site. However in the mean time ill just try to get my z running well, and listen and learn.

Looks good! I Love the color. quick question tho with the fiberglass and bondo mix on the rear end dont you fear that cracking? I only ask as I am looking into this option for my cars rear end, and to this point that has been the only thing holding me back from shaving it.

jnjdragracing do you have any information about your box? How did you set up the venting?

Darius the car looks amazing!! Keep the pictures coming! Just got three little questions 1.What kind of tubing did you use to make the supports for the body kit 2.Which front end did you run on the “old†Z? I can’t seem to put my finger on it. 3.It looks like you used a sub frame mod much like Petes, what other structural modifications did you perform? How do these differ from the “old z� Can’t wait to see your car in action!

Darius the Z looks amazing!!!! Like jmortensen I am also very eager to see how your exhaust is routed and what dia tubing you are using. Amazing work !

Pop N Wood i wish it was that simple. However the bolt circle dimater and the pilot diamter align perfectly. That is what is confusing me. somthing besides the bolt size should be off but its not. I guess its find a new flange or bore mine out 2mm per bolt hole.
