I'm aware of the Tach Adapt product but I still need to find out what wire or wires feed the tach itself. 01 Boxster S 6 speed. I have the Bentley manual and wiring diagram but my eyesight is just not that good anymore.....
Thanks for any thoughts!

I am leaving the factory ECU in tack so I can run all these little things like coolant temp yada yada. Might not be the "cleanest" solution but I think it should work.
If leaving the ECU in place doesn't work; I'm gonna follow this thread for a solution.
