I've found a lot of references to this product, but does anyone know the maximum mounting depth that will fit into the MSA rear speaker panel? This is for a '75 280Z. Thanks for any help!

'73 240z, pulled out the tach to fiddle with it because it only worked when it wanted to, fixing it up went marvelously because all it needed was some sanding down of the copper contacts to remove oxidation. NOW, putting it back together I've got four holes in the back of the tach for two backlights and two turn signal lights, and lo and behold I've got two backlights and two turn signal lights in the dash harness to shove back in those holes.... AND ONE MORE! Now I've gotten out my mirror-on-a-stick, shoved my head in any holes I can fit it in, searched forums, the factory service manual, and a crusty old Haynes manual and I'm not getting anywhere on this. It has it's…

Getting the engine bay ready for soda blasting and am replacing the engine harness. Im having trouble finding where the harness connects to. I can't find it on interior side of the firewall. Is this something I have to take the dash out to get to? I found some connections below the dash, but this seems to be to a different harness. Thanks guys

Hello guys! As you can tell I'm new to the forum, but am already finding a lot of useful information. I have a 1970 240Z (6/70) that I am beginning restoration on. The original engine had a connecting rod sticking out the block so a engine swap is in progress. When I pulled the engine I noticed the engine wiring harness has been tampered with severely. It has butt connectors throughout it and numerous homemade connections. Easily said, it's not up to par. I've been trying to locate a new engine wiring harness and have seen reference to a difference between the 240 years. Does anybody know what's makes the 1970 harness different? I've found other years for sale, b…

I am trying to convert my early 260z over to the 280zx alternator. I have found write-ups for the 240z and the 280z but have yet to come across a definitive write-up for the 260z! I need to finish this conversion asap because I have work in the morning! If anyone could lead me in the right direction with this I would greatly appreciate it! Thanks

So I was cleaning my sensors bc my car is running a little rich and my temperature sensor switch the one with the 2 wires connected to it one is te ground and the other is connected to another wire and the ground wire broke off totally from the tip of the switch. I researched to buy a new one and it looks like no one have those anymore. Can I run without it grounded or is there any suggestion you guys have? Please I need help. My car is a 76 280z

Hi all, My alternator stopped working yesterday. When I wiggled the L/S connector, it started working again. I had assumed it was a corroded contact at that connector. Then I started thinking about it. The L is simply the alt error light signal, which did correctly cause my alternator and brake lights to glow (no bad connection there). The other is the sensing line, which provides voltage feedback to the internal regulator. If that were momentarily disconnected, wouldn't the sensed voltage be zero, and therefore the output of the alternator at its maximum? At the time I was incorrectly thinking of the S as a field wire and thinking, "Ah hah! No field, no output!" …

Good morning everyone and happy Thanksgiving. I just bought a 77 280Z and it is in pretty good condition over all. The thing is, I am not a "car" person. I thought I would enjoy getting into it but I am in over my head on the electrical. There are so many great posts on here but they are not working for me. I can't seem to figure out how to start a post either! I was hoping that someone could steer me to a good shop in Oregon that could look over the wiring issues in my car. Any help would be appreciated. John

First off, I am totally ignorant when it comes to electrical issues, I can diagnose most mech issues but electrical, I'm lost. I recently finished a major redo of my 75, put the engine and tranny back in and reconnected all the wiring harness. Prior to the redo, the car started and ran fine. Now the starter won't spin, the fuel pump runs, lights work, but nothing else. I do hear a solenoid click, but its not the starter. The only electrical I changed was the coil. There is a wire on the passenger side harness with a loop connector that I believe goes to the starter solenoid with the battery hot wire. I tried disconnecting it and then nothing worked.There is also 2 red w…
