Hello everyone, I have been in contact with Klearz about making just the lower rear amber lens for 260z & 280z's and if we can get 5 people interested, the cost is down to $70.00 for the pair. This is alot better then spending $250.00 plus. I am really interested and ready to purchase. Anyone else interested. Skip

Line to fusable link

Im hooking up an EFI system in a 260z. On my L28E diagram it shows the power for a relay coming from a fusable link. The relay is not physically in the engine bay and I am not going to run a wire out to the physical fusable link. Which wire would be best to wire it to? The white power wire that goes into the voltmeter, or the white/red one which comes out of the voltmeter and goes to my alternator. Does it really matter ? Cheers

I had tried to start my 240 after a few weeks in below freezing temperatures. When cranking it over, (it took some time to start) I noticed that there was a little bit of smoke coming from the battery area. It stopped quickly and the car started. I did a quick visual check and didn't see any problem. The car idled for a while and I then took it out for a quick drive around the area. When I got back, parked in the garage and turned it off. I looked again at the battery and noticed that the top of the battery had water on it. Not a lot, but a few sprinkles. As I inspected closer, I heard a sizzling sound and the side of the battery had expanded on the negative termin…

auto shutoff for electric fuel pump

I've got a 73 that I've replaced the mechanical fuel pump with an electric one and I'm looking for an easy and effective automatic shutoff for the electric fuel pump incase of a wreck. My 78 has an oil pressure switch with two prongs on it, one prong goes to the pressure guage and the other one is closed if there is no oil pressure and that shuts off the fuel pump. Any chance I could just changeout the oil pressure switch for one from a 280 and wire it in? I know the 280 has a circuit to bypass the switch for starting and the 240 has the carb bowls that would hold enough for starting but I guess I might need some type of momentary pushbutton to run the fuel pump fo…

83 280ZXT radio packed up!

Hi...I've an 83 280ZXT, and when I turned the key to acc position 1, the point at which the radio/subwoofers/antenna go on, the radio played/displayed a few secs then went out/no display, and I've not been able to get it going since! I checked the radio fuse, as well as the other fuse the self powered sub amps run off of and no burnt fuses. The subs powered up along with all other acc position 1 devices, so I am pretty sure there's nothing wrong with ignition power relay, and I am pretty sure no aftermarket fuses were wired into the radio, only underhood relays for the amp-which are ok too! The antenna doesn't go up, though, which is to be expected, I guess (assume the…

Does 280Z Have Wiring for Fog Lamps? 1 2

Most newer cars have wiring installed for all the different options you can get- you just need to put in the switches & stuff. Does the 280Z have wiring in place so you can install some driving/fog lights?

DO something like GY(greenyellow) to R(red), BW(blackwhite) to L(blue), etc. Thank you so much... Oh, hey, maybe send a picture for reference...

Good day, I finaly got my Z to run. Now I am having a problem with the exterior lights. When the engine is running all the lights seem to have a strobe effect. Could this be the voltage regulator or the alternator? Also, my headlights come on and off when they please. the fuses are new and so are the bulbs. Any suggestions? Thanks.

Coil Shock

The MSD 6AL ignition is installed, the car runs like a champ and all necessary grounds are connected. When the car is running and you touch the coil you get shocked. The wire from the distributor to the coil is connected tight. The coil is a Crane Fireball PS-40. Could the coil be going bad? Don't know if it's always been this way because I've never touched the coil when the car was running. Any ideas? Vicky

Hello all. I recently bought a 1971 240 to play with, not a serious restore, but more of a fun car project. It has a good bit of rust in select areas of the floor and in typical areas under the body, overall its in decent shape to start with. vin number is HLS30-06201 for those who like that sort of thing :knockedou .. my first question is brake lights, turn signals and headlights. the previous owner has put in a switch to operate headlights separate from the stock switch. Is this common to do? also my brake light indicator on the speedometer works when i press on the brakes and use E-brake, but the rear brake lights do not come on when i use brake. all lights on the car…

Well I just wrapped up my final semester of school, and what happens to me on the last couple of days??? Electrical problems... Heres what happened, and what continues to happen. My 74 260Z, All of a sudden, has lost all tach, fuel gauge , oil gauge and fan function. And my amp gauge reads a varying drain, even when the car is revved. Upon a glancing observation I found that all the gauges use the same green-white wire. Continuity was... continuitous( is that a word?) through out the harness, however after the plug box I lose track of the wire... My question(s) 1) WHats going on here?!?. 2) Where is the beginning of this green/white wire. 3)am i on the right track?? Oh ye…

Hi all - I'd love some advice on my '70 240Z. I replaced the distributor, had a new ignition coil installed, the SU carbs rebuilt, and spent last weekend sitting in the hatchbay replacing the rear electrical harness so I can have rear lights. This weekend since there's no football, I plan the herculean task of going through the engine bay and tracing out wires that have been painted black and will need to cut and splice wires from a replacement harness I obtained so I can have a neat set of wires (I don't have the intestinal fortitude to dig under the dash and remove the entire setup from there, plus, I've gotten pretty good at cutting and splicing). When the distributor …
