1st off I have a 1971 240z 2nd my hazard lights work fine 3rd Turn signal switch only has three wires to it. Green, wht/blk and wht/rd must be from a later model of car 260z most likely. 4th Combo switch is probably from 260z also, it has 12 wires to the singe connector. There are three extra to my harness that someone spliced the plug in on both sides. I just looked at a unmolested 240z plug and there are only 6 wires to the main combo switch connector. These are the following wires that are loose from the 71 wiring harness. Some I know what they are for, others Don't have a clue and the crappy wiring diagrams don't show them. For Turn signals: Gr/Blk---- right rear b…

I've read a lot of threads here about upgrading a 240z's ign to electronic with a 280zx dizzy. I decided to upgrade my 73 the same way and got an 81 dizzy on ebay for ~$20. I know that the later 280zx modules won't work so I looked up the part on the Autozone website (and Checker) and found that they list the same part number for 79-81, the picture on ebay didn't show the module clearly. Well as many of you have probably guessed, it's the wrong module. Before I start looking for the correct module I want to make sure that there's no way the 81-83 type will work. If it will work is the wiring the same? It looks like there's a second connector on the 81-83 module vs the 79-…

So this Monday, I'm headed down to Dave's (Zs-ondabrain) place to overhaul the electrical system in my 1970 240.

I just bought an electronic ignition set-up that I think came out of a 77 or 78 280Z for my 240Z. I got the new dizzy, EI module, new rotor and new cap. My car ran before I tore it down, so the original points ignition still works. My question is, would you leave the points ignition in and get the car running again, then do the upgrade with the motor back in the car, or is it such a major improvement (and as simple as the seller described it) that I should go right to the EI now?

Hi all, As the subject says, 1973 240z stock ignition (well, a better coil, but the rest looks OLD). The car has run fine for months, no problems. Yesterday it cut out, and was hard to start. Seemed that there was no spark, checked it and it didn't. After a bunch of tries, it started, only to shut down suddenly. After wating a bit it started. Now, even when cold, it will sometimes run for a while, then immediately stop. Unless I turn the key comepletely off, it won't start again. Not every time will it start again right away. Runs from 10 seconds to 1 minute before stalling. I checked all the ignition wires, ran a few tests from Chilton's, the only issue I see is that the…

I am trying to start my 82 zxt parts car engine. It has not been started for at least 6 years. I changed the oil and filter, put marvel mystery oil on the cylinders (through the spark plug holes), and have drained all the gas from the tank and refilled it. I left it rest for about two weeks thinking that the mystery oil would have a chance to work it's way around the rings and perhaps even down the cylinder walls before I tried to start it. After installing a fresh battery, the ignition switch would only make a faint clicking sound that I don't believe was coming from the starter. So, I then removed the old spark plugs and shorted across the two large started posts with a…

Hi Fellas. I just bought a set of NOS Datsun Competition Sparkplug Wires on Ebay for $35 bucks (shipping included) and like to know if anyone is currently using these on thier Z or used them before. see attachment below -> Any recomendations on what Cap and Rotor would work best with them, read on the forum not to use with MSD of some kind, "..not recommended for use with the MSD box.". Is it also true they interfer with the radio signal? Figured they'd be good spark for the engine rebuild. ~Z~

So I replaced the horn relay, and still no horn. Works when I run juice through the wire going to the horn, so I guess that's a good sign. Maybe it's something at the steering wheel end? Here's some pics. I have everything (I'm assuming) but I'm wondering if anything's supposed to go in those other holes. Anything supposed to go in those other holes? Side view with green/black wire that goes to the relay, as far as I can tell. Does anything look wrong or out of place?

Hey guys, just looking for the horn relay. I'm assuming I know the general location, so which one of these is it? The previous owner did some intersting wiring, so I'm in for some fun in the near future... Same location, just a different angle.

I'm having an electrical problem, and I hope someone can point me in the right direction or give me some better troubleshooting tips than what I currently have in my toolbox. I have a reasonably stock 240Z, with an upgraded alternator (ZSpecialties 105 amp, internally regulated). I drove my car to work on Thursday, and then used her to run a few assorted errands (I figure I put sixty miles or so on the car that day). That evening, I took her out again, and she started running very rough and the gauges started jumping all over the place. I finally babied her off the road (luckily I was on a downhill at the time), and after finally dying....she refused to start. I tried to …

Hey guys, was messing with the car today and the headlights worked the entire time I was messing around. Went to put the car back in its spot, turned the lights on and they stayed on then flashed and wouldn't go back on. My first thought was the fuses, but the connections in both the headlight fuses are still fine. All the other lights on the car work but just the headlights don't seem to work. I was reading around on here and most people seem to say that there low beams die but the high beams still work. I will have to see if thats the case and I might run outside to try that now. I did have the ignition switch cover off, but I dont really think that effected it. What el…
