I'm currently in the middle of restoring/modifying my 1974 260Z as my daily driver. Nothing over the top, just a ride that will keep me smiling when I'm on the road.
Planned modifications:

-header-exhaust system, 2.5 inches wide
-4 piston front calipers
-rear disc brake conversion with 2 piston calipers
-ZG Fender flares + BRE style spoiler
-JDM Fender mirrors
-BRIDE GIAS II reclining bucket seats

Current issues
-dead tachometer, worked once, then just died. Unknown cause.
-rust hole in the floor

My main question is about the tach, does anybody have an idea what could be causing it? I have checked wiring diagrams and my battery is only about a week old. Thanks in advance! Will be updating the thread regularly.

Make sure your coil polarity is correct and at the big resistor next to it. The tach reads the + signal from the coil. Also in line with the tach feed under the dash is a small resistor that could b but likely bad. Or the tach simply died.
Good luck with your build and welcome to Zdriver!

Thanks for the advice! I'll try those ASAP and see if it gets the Tach working again.
