i have a modest sound system. 4 speakers total and a CD player/head unit. No amplifiers. Was working fine, now all speakers have this terrible sound coming out of them that sounds like a mix of static and cracking. Its not a stereo ground wire. Some web research said it might be either the battery, starter, or alternator. Anyone have any experience with anything similar?

Hi, I am planning to upgrade all fuses and most relays in my 1977 280Z. Are the any good modern standard replacements for the Fuel Pump Control Relay and the Electronic Fuel Injection Relay? Or is the only way to achieve the same function by using multiple standard relays? Thank you for your help.

Hello, does anybody know what contacts are the correct ones for the 280Z 35Pin ECU connector? It is an AMP connector, but I cannot find the correct contacts. At first I thought it were the Junior Power Timer contacts, but they don't have the exact same dimension - they seem to be a little too small...according to the drawing that I found. I would like to completely rewire the injectors. Thank you for your help.

My car just started making a very odd sound when it turns over. It sounds like a spinning tires. only until the car fully cranks up and then sound is gone. Any ideas. I will try to get a quick video next time i crank it up.

Guys I am lost here. I was putting my AC console all back together and AC did work when it used to just a day ago. When i turn the switch...nothing. In image 2, this came loose. Looks to me like a ground? Also it comes from wire harness that connects to AC switch. I found a hidden fuse i didnt know existed. It was blown, photo 1, numbered 3. I had ignition on and the above shown wire in photo 2 not grounded. I put a new fuse in, it got orange hot and blew. I turned ignition off. I grounded that wire, hopefully right thing to do? I then put in another fuse. It blew too. Any thoughts. btw, i have 2 connectors number 1 and 2 that dont go to anything. cur…

My friend has a '75 280 that had a crane x700 spark box on it which we removed. After reconnecting the stock ignition system we noticed the ballast resistor had been removed by the PO. Using the 12v coil the crane module used, would connecting both power wires to the positive terminal cause any long-term damage to the stock transistor ignition module? The car runs when wired that way. If running it that way will cause an eventual issue on a '75, what did Datsun do to the '78 model since that was the only year that didn't use the ballast resistor?

Ok, I’ve started wiring the alternator in my 1977 280Z. I’ve noticed a huge issue: the wiring harness has two wires and T-Connector, while the alternator has four pins. Im not sure as to the type of Alternator, but would a new compatible voltage regulator be needed to make this work? thanks in advance!

I have been working on creating a comprehensive diagrams so I can rebuild all of my wiring and I could really use some help with the last couple of details. Context: The previous owner sold me the car largely disassembled so I have had to chase all of the wires and connectors and figure out what they go to. In the process of doing that I discovered that my engine harness is for an automatic, but I have a manual car. There are also a couple of wires that were snipped. The first thing I need to understand is what one of the cut wires is for. It's a thin black wire (approximately 14 or 16 AWG) and comes out of the main trunk of the harness near the Seatbelt Relay c…

I have a 1977 280Z, and it (or I rather) have an unusual problem. The red brake light indicator will not go off. But here is the kicker. When the parking brake is fully engaged the light is very red, release the parking brake and the brightness diminishes quite a bit (but it is still on). Any ideas would be appreciated. Thanks, Jim

I have my antenna hole rubber plugged. But i have the original antenna with cable and i think it all works (i am missing the outer chrome portion that screws on outside car). Wondering what others did. Did you go with A stationary antenna? If you used original where did you mount the electric button to raise lower antenna. I dont have original radio, but a newer one. So would need some kinda button if go electric route. Or did you just rig it so when the radio is turned on the antenna raises and lowers when turned off

Many of us have used VC for electrical connectors, especially for 240Zs. They announced that they will need to increase prices in February, and they encouraged people to place their orders before the price increase. Fortunately for me, I just restocked before they announced the future increase.

I’ve never seen these mounts on the front of a 240z before. I’m thinking it is a fog light mount/bracket that also relocates the horn? Wiring for both stay in the same general area? Canadian model? Looking for input.
