You don't need to pull the dash to remove the gauges if the car is stock. IIRC the FSM has instructions on removing the gauge. You definitely need to detach the heater control cables. As for feeding back the signal. Don't. Get the gauge out first. Then you can set up the test. You will need to set it up like the diagram the Captain posted to test it properly.

S - Sense (connects to the battery) L - Lamp (switched) https://auto.howstuffworks.com/alternator2.htm

The positive side of the fuel gauge is the yellow/red wire. Since that wire also powers the oil pressure and water temperature gauges, you can eliminate that as the source of your problem if those gauges are working. The likely culprits would be a poor connection between the fuel gauge and the dash harness or the fuel gauge itself.

Here's the video we made for the car.

Find this connector between the dash and body wiring harnesses. Check the yellow wire there. If you have a signal there, look for continuity on the yellow wire through the body harness. So it ended up that we did find out what was wrong with @GeoJoe's fuel gauge. I checked continuity on the yellow wire on the body harness. It read open line. The wire was replaced, and the gauge works.

A friend entered one of his Z cars into the Hot Wheels Legends Tour. (Ignore the reference to the wrong Peter Brock in the story.) https://www.fox5atlanta.com/news/alpharetta-man-competing-to-turn-his-car-into-hot-wheels-toy I'll be watching tonight to see if it shows up. https://www.facebook.com/events/708765086450998

Send me a PM with your email address. Someone pinged the GZC group today looking for a 2+2.

Here are a few photos from the enduro race from Sunday at The Mitty. Greg Ira and Woody Staub piloted the #5 Dan Parkinson tribute car to a 3rd in class finish.

Thanks, Guy. The 46 is still out at the Z Car Garage, but the repaint is complete, and the hardware is getting installed. I think Randy is more focused on getting the LSR Z ready for Amelia. Yes, the 22 is prettier than the 85, but Guy seemed to be doing a pretty good job of moving around the track in the 85. I'm sure it didn't hurt for Guy to get some laps in Greg's car during the enduro race on Sunday.

Look through Blue's tech tips. The link is in my signature. (Make sure you read this on a computer rather than a phone so you can see the signature.) He has documented what to do for the 75-77.

Okay, so this is not "vintage" with respect that it happened today, but here is Greg Ira battling Doc Bundy in a Group 3 Sprint Race at the 2021 Mitty. Greg started 5th or 6th, battled his way up to 3rd, and finally got up to second. This is footage from turn 10A/B at Road Atlanta on the final lap.

It had a couple of friends join it. My Mitty buddies who aren't racing don't get to the track at 8AM like this nutcase does.

I finally got out to Road Atlanta for the first time since the 2019 Mitty. It was good to be back at the track. The Z car count was down, probably due to Covid and the 100% chance of rain on Saturday. Greg Ira kicked @$$ today in his sprint race over some fast competition in his Dan Parkinson tribute car. Woody Staub, a friend of @Diseazd, went from 11th to 6th in the same race in the #85 car.
