Posted November 10, 200717 yr comment_228042 I changed my speedometer and my dash lights went out is it because of the different spedo or is it a fuse? Link to comment https://www.classiczcars.com/forums/topic/26182-1974-260z-dash-lights-not-working/ Share on other sites More sharing options...
November 10, 200717 yr comment_228045 most likely a fuse problem. The parking lights are usually on the same circuit so if they are still operating, it may not be a fuse but the dimmer under the dash. Also known as a Potentiometer. It's 33 yewars old and you may have shorted it out in the process of the "swap".Check the other lights, the dimmer and ALL fuses in the fuse box, both visually and with a ohms meter.Let us know what ya find,Dave.

November 10, 200717 yr comment_228053 not knowing the 260Z's that well, my best advice it to look for similar plugs in that general area. It most likely got disconnected in the fight to R & R the gauges.Dave.

November 10, 200717 yr comment_228056 the dimmer is usually located under the Tach but I know 240Z's, not 260Z's. I can imagine that it would plug into the Speedo, on any car.The plugs have to be there somewhere. keep looking.good luck,Dave.

November 10, 200717 yr comment_228073 There's a two wire plug in the speedo harness that plugs into the light dimmer - resister Wire colours red with blue tracer and black This is looking at a 260 speedo Link to comment https://www.classiczcars.com/forums/topic/26182-1974-260z-dash-lights-not-working/#findComment-228073 Share on other sites More sharing options...
November 10, 200717 yr comment_228096 If it's like a 280Z, then the dimmer control's connector is a 2-pin white plastic connector under the left eyeball vent. The mating connector to the dash lights should be nearby. You will probably need a light to crawl under there and look for it- there's a big mess under there! (At least mine is.)This is a good incentive to get yourself a copy of the wiring diagram for your car, especially if you intend to keep it a long time.thxZ Link to comment https://www.classiczcars.com/forums/topic/26182-1974-260z-dash-lights-not-working/#findComment-228096 Share on other sites More sharing options...

November 10, 200717 yr comment_228112 "to a plug on the speedo??" I hope you didn't fry your speedometer! The dimmer control doesn't have a plug that goes to the speedometer. It goes to a mating plug that's in a nearby group of wires. If that's what you did, and the light still doesn't work, you might try bypassing the dimmer control. You'll need a wiring diagram to see which pin to use, then connect it to ground. Then if you still don't have any lights, you're in trouble...
