First and foremost, I have searched multiple forums and believe I do in fact have the correct dashboard wiring harness, but due to the multiple part number changes, I thought I would confirm with the community before embarking on the dash removal Background: Last night I went to replace the gas gauge in my 6/70 Z. To my dismay and utter disappointment, the dashboard wiring harness currently in the car has been butchered and all the wires have been spliced together. Everything works except the gas gauge and all the radio connections are destroyed. i want to install the original radio when I replace the gauge, so installing the new harness is the only solution. Solution…

Almost done with my 73 resto. Everything electrical is now in working condition. Can get the hazard flashers to work. All connections triple checked and cleaned. Dash hazard switch also cleaned and does look in good working condition. Any suggestions ? Any such thing as generic hazard relay (the one by passenger side) ?

HI, This is my first post here. I have a 1972 240Z. It's story from my attaining it is chronicled here --> Linkhttp://www.cardomain.com/ride/2977492 The car has been at the mechanics, a Specialty Z Shop, since around Thanksgiving. The car has had a new engine installed and just about everything else one could think of mechanically, has been replaced. The car won't rev past 4K. Carbs have been swapped, fuel system bypassed(for testing) coil, distributor,points/pertronix, all have been changed out, even the tach. Wires to and from the coil and distro have been checked/replaced. My Q: Has anyone experienced this problem before? Follow -up Q: What was done to correct it?…

Hi all, I am finally making good progress on the 240 and am VERY close to firing it up for the first time. I have done a lot of searches, but this simple issue eludes me. I have installed an aluminum radiator with electric fans. I have a thermostat control switch with a relay for the fans. There is a constant power source to the fans directly from the battery, but there is also a lead that needs to be attached to an ignition based power source. Here is the dumb question: Where can I find an ignition power source? There are no extra connector points on the fuse block (all of my old cars have had 12v spade terminals available). Just the basic glass fuses. I have added…

Does anyone kow what I need to do to fix this problem?

So I have a little problem I cant turn on my headlights on my 71 z. If I remember correctly I used to be able to fiddle with the light switch on and off and eventually the lights would come on. This was about a year ago. I have since gone away to school. At some point when I was back I realized that the "on and off until the lights come on" tactic no longer worked. I found a blown fuze to be the issue. I replaced the fuse but as soon as i turned the ignition to acc the second fuse down on the right blows(I cant remember if that matches with the left or right headlight at the moment). Anyway, I followed the wires as best as I could, and didnt find any damage or short…

Everything was working fine on my 70 Z, until we were taking it off the dyno the other day. Now, the rear tail lights don't work when the headlight switch is activated, brake lights don't work when I hit the brakes, but the front parking lights and instrument lights come on when I hit the brakes!! I would appreciate any ideas you guys might suggest. Thanks Guy

Hey Z crowd. I just pick up a beautiful dust blue '76 Z last week and already have a dozen parts coming to clean her up (new carpet, power window kit, etc). I have an MSD 6AL controller and Blaster 2 coil from a Chevy 383 stroker that I'm no longer using and figured, why not, throw it in the Z. My research has brought me to understand that I need a tach adapter to make the 5v square wave from the MSD work with the 12v sine(?) wave needed for the tach and fuel injection of the Z. The adapter MSD forums suggested was the 8910. They have about $50 for it. Thing is, if I could get a schematic for the adapter, or a similar circuit, I could simply build my own. I've noti…
