On my switch there is one wire going to it. It looks like the other wire, as in pic, is broke off. I see switches on ebay that have two wires going to it. Should that other wire be connected to the switch? On the wiring diagram I see two wires going to dimmer. one is red, with white stripe. Other is red with blue stripe. Is that the switch on the wiring diagram? Thank you very much.

These two wires are in the wire bundle that goes to fuse box area. The same bundle that has the big white wire with red stripe- as in pic. I don't see them in any wiring diagram. What could they be for? Thank you.

my 78 280 rear hatch defroster doesn't work - all the horizontal filaments are compromised in one or more locations. there is power at the clips up on the ceiling and the console switch works fine. i drive the car every day and in seattle winters the hatch glass is constantly fogged. i upgraded to a honda blower fan, which will eventually de-fog the rear if i blast the defroster on high, but it's so slow getting the warm air back there that i often reach my destination before i can see adequately out back. my idea was to mount a cheapo 12v defroster fan to the back panel that covers the tail lights, pointing up at the hatch glass and hopefully do a better job of …

Would anyone happen to know the location these bulbs go on the speedo ? One bulb has a red with blue stripe wire and another bulb has a red with blue stripe wire. One bulb has two wires, one is red and the other is red with a white stripe. The other bulb also has two wires, one is yellow with green stripe and one is green with yellow stripe. Thank you.

Hi Everyone, I'm installing dual electric fans in my Z shortly and was wondering where the majority of people put their thermo switches. To my understanding I would want this to be the engine temperature and not the coolant temperature via the radiator bung. Does anyone have any suggestions or input? Thanks! Chris

Hi guys I need some help. No power at turn signal lever its 73z manual when I picked up car it was a bare shell only, all apart, does anyone have a photo you can share of where the wires from the combo switches meet up? I have the signal switch plugged in to the right plug on the main harness of dash which looks like it's a square plug with 6 pins, but there's zero power there. And zero at the lever. There are a couple of single wires unplugged like the key buzzer wire which right now I'm not worried about. I think some of them crossover from headlight combo switch to the tsig side, but colors don't match under column. The other lights all …

So I find myself building a headlight relay upgrade harness for the 71 project car I'm working on. I've been making my own for a long time, can't justify the $158 USD cost of buying one from MSA. Especially with the exchange rate the way it is. While building this one, it reminded me that a friend had asked me to build him one for his '76 280 last fall, so I thought I should do two at once and save a bit of time. Then I remembered the "detail" that makes the 280Z harnesses a royal pain. There are no sources for the round 4 pin weatherproof connectors that the 280's use to make the harness plug and play. You are forced to hack into the harness or replace the plug…

Just purchased this Pertronix Ignition Coil model 40011 which is rated 1.5 ohms and was wondering if it is connected correctly to the ballast resistor and to the eléctrical system. I am also concerned if i am missing any washer or plate which is fastened to the ballast resistor as i want to have a secure and long lasting coil. Do i need to add any additional protection?

I'm doing the voltmeter for ammeter swap. The 71 240Z has a yellow with red stripe and a yellow wire. I think they're yellow. May have been white at one time. May have yellowed over time. It also has a black wire. I already connected wires for the voltmeter (not in the pic). The wires in these two pics are for the fuel guage. In the other pic there are green, yellow and black wires. Does it matter how I connect the green and yellow wires to the 240Z wires? Green to yellow with red stripe or green to yellow? Any help? Thank you very much.

Keep trace diagram and simplified how I should connect '77 Voltmeter replacing with '75 ammeter. 1. Connect Black and Black line on Voltmeter. Both goes to Ground. 2. Add bullet male connector for Green/White line on Voltmeter. 3. Extend White/Red line to fuse box and connect to IGN after fuse. I might just connect W/R, W, and G together to fuse box that connect to IGN line.

I am about to order a Pertronix coil model 40511 which is 3.0 ohms to be used with a Pertronix 1761 ignitor module installed in my distributor. I was wondering if it was better to go for the 1.5 ohms versión and connect it to the stock ballast resistor as it would protect the coil from overheating? Any recommendations on this.

It's been long time. Finally I got some spare time while Xmas holidays and I was working on ignition. My 280z is '75 none CA model. I can't get spark. I unplug spark plug and wire and leave it near strut mount top and turn on key to ignition position. The starter motor is clanking, but no spark. Where should I check? I have several modification on wiring. I removed SHUNT and directly connect the line Red/White and White line. I removed External Voltage regulator and install CS-144 Alternator. But I don't think this is related. I check fuse, all looks good. I replaced fuel pump and fuel pump is wor…
