I’m looking to find a tach signal for a shift light or a new tach. I have seen the adapters that they have out there for some vehicles and maybe that is an option but I hope there’s a simple connection somewhere.
I'd check with the manufacturer of your Tach/Shift light. There may be a switch or setting to tell it if you've got a 4, 6 or 8-cylinder vehicle.It did not work. When the factory tach was up to 3,000 the new tach was only up to 1,000. I also tried a shift light I have and same thing. Bummer
