    Heater Hose Firewall Grommet '75 - '78

    Oh man, those look identical. Unfortunately I ended up grossly over-paying for a new one from JDM-Car-Parts.com. Awesome that they have new ones but yeah I am sure I could have snagged a much cheaper junkyard pull from one of those. Great info though!

    Speedo/Tach Lenses

    wal280z - Thanks man! I did end up getting some lenses from another member though so feel free to give them up to whomever needs them.

    '78 280Z Fast Idle Actuator

    It is vacuum operated and triggered when the A/C compressor is turned on. I am not sure how the Vintage Air system works but I would assume it's all electric? I suppose you could get an electric vacuum pump that is triggered by the power wire for the compressor if that's the case.

    Heater Hose Firewall Grommet '75 - '78

    Looking for the rubber grommet that goes around the heater hoses on the firewall. Anything from a '75-'78 Z should fit. I don't need the metal cover just the rubber piece as mine crumbled into pieces when I took it off.

    Speedo/Tach Lenses

    Tried to restore my speedo/tach plastic lenses on my '78 280Z with a headlight restoration kit and just made them worse haha. Looking for new ones, preferably nice and clear without a bunch of scratches. I don't need the whole gauge just the clear plastic lenses. They are the same for the speedo and tach so if you have two tachs or two speedos lying around that works too. And although the gauges themselves are slightly different I believe any model year has the same plastic lens. For price/shipping purposes I prefer to buy just the lenses if possible but if the price is right I don't mind buying the whole gauge. They don't have to work.

    '78 280Z Fast Idle Actuator

    Looking for one to complete my factory A/C rebuild on my '78. It's one of the ugly things that bolts to the intake manifold...

    '78 Factory A/C Relay Wiring Questions

    Awesome, thanks! It's all making sense now!

    '78 Factory A/C Relay Wiring Questions

    Thanks! I must admit I still don't fully understand how that is the conclusion but I will take your word for it! I would like to learn more about this part of things as it is admittedly one of my weakest areas of automotive knowledge so if you don't mind a few more questions I would appreciate the lesson! My confusion lies with both LY 12V power lines being constantly fed power from the fuse box. if the power to the coil is constant wouldn't that mean the relay is always triggered? In it's normal state shouldn't it not be getting power until the switch sends power to it triggering the relay? Clearly I am not understanding something here as I don't think Datsun would have some sort of weird voodoo relay, but I would like to understand. From what I gather you have the power and ground to the coil in the relay. You hit the switch, power goes to the coil and creates the magnetic field that makes the connection between the constant power source and the thing you're trying to turn on. In this particular case is the F.I.C.D. or the Pressure Switch the key to how this all works? Does the coil not get ground unless the pressure switch connection is made?

    '78 Factory A/C Relay Wiring Questions

    Well you would think I would be able to figure it out, but I am either reading the wiring diagram wrong or not understanding how that particular factory relay works. From what I can tell LY originates at the fuse block so I would think it was power. Here's the wiring diagram for the A/C circuit...

    '78 Factory A/C Relay Wiring Questions

    Also in somewhat related news, the only other part I am missing is the fast idle actuator that bolts to the intake manifold if anyone has one they want to sell!
  12. CLIFFS NOTES: Has anyone replaced the factory A/C relay with an aftermarket relay? If so, what specs did you get and how did you wire it up? LONG VERSION: Almost done returning my 280Z to functioning factory A/C after a previous owner's questionable retrofit/repair job. One of the last pieces I am missing is the factory A/C relay. It is missing completely and it is super hard to find without spending $80+. Question #1 - Can it be replaced with a standard off-the-shelf relay? I would assume so, but I am not sure the specs on the factory one. Question #2 - How would it be wired? It's not super straight forward on the factory wiring diagram side. I have stared at it for hours and I can't confidently figure it out. There are 4 wires from the factory, 2x LY, L, and Y Usually on a relay you have constant power, power from the switch, power to the component you're trying to turn on, and ground. I am no wiring expert but I cannot for the life of me figure out how the factory wiring diagram gets all those things to the relay. The LY wires appear to be the power wires from the switch. It can be traced from the fuse box to the blower motor and a/c resistor (switch), then it runs to the relay where it splits into 3. Two of the LY wires go to the relay, the other goes to the F.I.C.D. Why are there two LY wires going to the relay when the originate from the same main wire? The L wire, this one is pretty clearly the power to the compressor and it also branches off to the F.I.C.D. The A/C is switched on, the relay triggers and sends power to the compressor and F.I.C.D. Got it. That's the only easy one. The Y wire goes from the relay to the Pressure Switch. Which one is ground? Which one is 12V constant? It's driving me crazy! Thanks in advance for any help!

    WTB: Sun Visor Clip (280Z)

    Looking for the piece that sandwiches between the rear view mirror and the roof that's sole purpose is to hold the inside posts of the sun visors. Went to pull mine off so I can change the vinyl that's behind it and it completely crumbled apart in my hands. For a 1978 280Z. Thanks in advance!

    WTB: Heater Control Valve ('78)

    Looking for a working heater control valve for my '78 280Z w/Factory A/C. Mine leaks all over the interior. ZCarSource.com will rebuild it for $180 but I figured I would try and see if anyone would sell me a good one first. Mine is still burried under all the dash stuff so this is a link to the ZCarSource page so you can see a photo of what I am looking for... https://zcarsource.com/rebuilt-280z-heater-control-valve-for-the-1976-78-starting-in-august-of-1975-datsun-280z Thanks in advance!

    Hello from Las Vegas!

    Thanks! It's getting there but it's nowhere close to how I have it pictured in my head. Baby steps!
