What I meant was the ignition switch and accessories worked normally without the ECU wire, but when the ECU wire is tapped in the ignition and accessories don’t turn off, almost like the ECU wire is supplying power instead of just receiving it.

I have an 80’ 280zx with a 82 turbo engine in it, I installed Godzillaraceworks prebuilt single coil megasquirt system. So far it’s given me a lot of issues. I finally managed to get it started but it runs rough at low RPMs (below 2500) and doesn’t idle. My AFR guage reads that it is running super lean, like 18+ I manually lowered the afr table but still nothing Also when I turn the key to off position it doesn’t turn off the car, nothing changes when I switch between off and run on the ignition switch, but as soon as I disconnect the ECU ignition wire from the cars ignition wire everything works normally. also the temp gauge isn’t working on the dash anymore if anyone can help with my issues I would greatly appreciate it
