I hope to make this a Sticky (Mike!!) I want to Document every S30 style combo and Turn Signal Switch. I need every one to see what is already posted and add to this Thread if you don't see your style of switches. With any luck, anyone can pick up a switch out of a box of parts and be able to cross reference it here and know exactly what they have. I am now in possesion of over 80+ switches that I would like to start rebuilding for people and customers. Only problem is that there are so many styles that I am not totally sure of what is what. So PLEASE remove 4 screws from the steering column cover, take off the top and bottom covers and......... Take a picture of....…

So, since I'm between shows, I figured I'd get a little bit of tiny bits dealt with. I figured I'd do the combination switch. Everything was going fine, got all the plastic cleaned up and polished, cleaned up the contacts on the headlight/wipers/washer side, and then an issue popped up. The washer button is sitting too deep into the wiper section. I looked at the video I took while disassembling it (I figured I forget easily so I might as well) and I can't see anything that would cause such a thing. I thought I'd compare the rod for the washer button and the tube for the washer handle to see if there was a difference in length and it looks like the washer button sit…

I was recently gifted with a box of S30 antennas and associated parts. I hope to refurb them and get them in the hands of new owners. Of three antennas with mast bases, one is marked Harada and the other two have no branding whatsoever. The branded and non-branded units appear to be virtually identical in all respects, except for branding. Both have what might be a date stamp. My question to the group is: did Harada produce non-branded antennas or was there another manufacturer involved building identical but unbranded units, perhaps under license from Harada?

Hey Everyone, I just replaced the stock distributor in my 11/70 240Z with a new 123Ignition unit along with a new Bosch coil. The car now runs great, but the tachometer no longer works. When the engine first turns on the tach jumps up a little bit, but then slams back down to 0 and stays there. Anyone have any advice on what I screwed up? Here's how things are hooked up currently (see image below for my wire numbering): [Black] The black wire going to the 123Ignition unit is connected to the coil negative [Black] There's another black mystery wire that was hooked up to the old coil negative, so I hooked it up to the same place on the new …

Hello, just want to share my today's experience - maybe someone can benefit from it. I recently had a heat problem with my combo switch connector so I replaced it and also had a go at refurbishing my T/S and combo switch. Everything worked fine and I was able to use my headlights again (one day I will add some relays there). Some weeks later I noticed that the voltmeter was behaving strangely. It was jumping up and down and then suddenly stopped doing anything. I checked the wiring diagram and saw that the hazards are also involved in that circuit and that the hazard fuse was blown. So I put a new one in and it immediatelly went up in smoke. After ripping apart…

I'm working on the map light in my 73 240z. The one in there was working but not now. It may be a replacement housing as the 2 wires (red & black) are spliced in. I am going to replace the bulb but the more I look at it the more questions I have. Does the map light have continuous power going to it through the red wire? Does it have its own line fuse? Mine does not have any power in the line even if I have the key on or lights on. Is the housing supposed to be black? Mine is white. Thanks!

I recently visited with @inline6 to see if I could help him with an issue with his wiper motor. Though we thought we fixed it, my meter readings said we still had a problem. It turned out to be a self-inflicted issue that @Captain Obvious helped me to understand. Thanks to @inline6 finding an old thread (linked below) and @Captain Obvious getting me to focus on the diagram in the FSM, I was able to develop a better understanding of how the wiper circuit works. I hope I can convey it clearly in this thread. Anyway, here is the thread @inline6 found: Page BE-17 of the 72 FSM shows the wiper circuit, but it is confusing because it is a challenge to relate the diag…

Can anyone recommend a turn signal rebuilding service? I would try it myself since there is lots of information here, but I am limited to one hand for the next 8-10 mths due to surgery.

Can anyone identify what this is and the purpose? 1973 240z-See photos. It's attached to the console under the dash near gas pedal. It has three prongs out the back. There is a three prong plug that may go to it, as it's just sitting there unattached for at least ten yrs. Wires are 2 black and one green. There was a dealer installed Ac that was removed and an aftermarket radio that PO had installed and butchered the wires. I have been slowly fixing them.

Thinking of getting the RetroSound RetroRadio M2B. Is anyone using one now and what is the opinion on it? I believe the last posts about this were 2010 & 2017 with faceplate issues. Looks like they make a universal one now. Link here- https://www.retromanufacturing.com/collections/vehicle-search/1973+datsun+240z+radios

Hey all! My 77 280z alternator and/or regulator have decided to go to Valhalla. I have a 280zx parts car with a good alternator so want to upgrade to the zx alternator which is internally regulated and delete the original external regulator. I've read all the DIY posts (which are all really well written) and am a little bit stuck. I'm seeing conflicting info on two of the best sites and wondering which is correct. I'm attaching pics from each site and pics of my connector in two configurations. Which is correct? I chopped off the regulator plug to keep keep the car-side harness intact so the colors don't necessarily jive (I think I had an aftermarket regula…
