I spent last night and the better half of this morning going thoroughly through all 73 pages of the electrical section of this forum.. I have a 77 280Z made in 7/77. I just scored a slightly scuffed harness out of a 10/77 so a 78.. I acquired the Fuel Injection Relay that screws in near the battery, The ECU numbers were the same, will this harness go right in? All i found was the AFM didnt have Fuel Pump Points, but my pump is on a toggle switch anyways. All help will be greatly appreciated, and Ive spent my time searching and not finding clear answers so please no Flames about searching. Im an AVID user on 300ZXCLUB so im very familiar with the search function.

I am putting in a new engine and before I reinstall my O2 sensor I would like to clean all the carbon deposits off it. Is there a safe way to do this without damaging the element?

My temp gauge and oil gauge are "pulsing" together in unison. They move up a bit and down a bit in a synchronized fashion every few seconds. My amp gauge reads 15 pretty much all the time, too. Would this be a sign of my alternator going south? Other ideas? All feedback appreciated. Thanks. Jeff

I bought this power antenna kit at Autozone for 59.95 plus tax. I thought I would try this after reading an earlier post from a member here who used the same kit. As long as you are connecting this to a modern stereo unit with the blue accessory wire, it's not too complicated. I just wonder how long this fine chinese made product will last. Here is a short video of the antenna working. http://www.youtube.com/watch?v=sG2S0M2hBEM

OK, now that I have my over voltage situation resolved it is on to the next problem. My horn and dash lights do not work. Headlights and map light do work. Brake light is working (laugh all the time the car is on) Not sure if the horn and dash lights not working could be caused by one problem or not. I will be looking at the rheostat for the dash lights. Comments? Any direction would be appreciated. Thanks in advance.

I've read dozens of threads trying to find the answer to this, but most seem to be discussing pairing it with the 6AL, Mallory distributor or upgrading older 240z's... Is the MSD Blaster 2 coil plug and play for my stock '76 280z? (L28 EFI) Do I need the MSD 8910 tach adapter and if so, where do I hook that up? Pics would be appreciated.

Before I sent my Z to the bodyshop I pulled the dashboard to fix some cracks in it. I then re-installed it and replaced all of the gauge bulbs and made sure everything worked before sending it to the shop to get straightened out and painted. The headlights, turnsignals front and rear, marker lights, brake lights, reverse lights, dash lights, hazard lights, running lights, interior lights, EVERYTHING WORKED! Of course I re-removed all exterior lights for the body guy before he got it. Now that I have the car back, I have been re-assembling it. A few days ago I had all of the exterior lights re-installed and working fine. Just last night I noticed the turn signals stop work…

Hi All, before it is too late, cloned the oscillator clock z of a rally with 2 knobs. where are the experts in electronics? oscillator provides the 12 Volt power supply, or perhaps reduces the voltage to lower voltage? generates a square wave with a certain frequency and amplitude. electronic components are cheap. Here are some passionate electronics or who works in electronics? Opinions? suggestions? everything is welcome. thanks

I've had some issues with the water temp switch in the past on my 260, and have put together the below in an effort to help other owners diagnose issues with the system. I'm no expert and it's certainly conceivable that I've made mistakes with the below, or missed something somewhere, and I'd be happy to hear about it. Keep in mind that the only year I've laid hands on is 74, so other years info is somewhat speculative in areas and has been gleaned from documentation sources. Also, if there anyone would like to add info for years 75-78, that would be excellent. Respectfully submitted.... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The Water Temperture Switch - What It Does: Star…

i need a replacement water temp switch for my 1976, but unfortunately nissan doesn't make them anymore and i can't find any third party suppliers. i noticed that MSA sells a water temp switch for a '74 that looks very similar to mine, albeit with different connectors on the wires. has anyone ever used one of these to replace the switch in a 280? do the threads even match? being that one is from a fuel injected vehicle and the other is not, would they function the same? here are photos of a 1976 switch and the MSA switch:
