Hi Guys
I have a shift light that only works with a ecu tacho signal, not a coil negative. Would anyone know where that is? or what pin on the ecu i should tap into?
Cheers guys

What ecu do you have?
If it's a Weber L8 you can get a signal off pin 7 on the ign. amp module.
If it's P8 some versions had a tach output off pin 7 or possibly pin 9 but i'm not 100% certain as within the same ecus the pins drove different things on different vehicles.

Yes, seeing as it's an L8 set-up connect the tach. wire directly onto pin 7 of the ign. amp, i did it on my non cos. turbo 16v twin cam 2.0 engine and it workes perfectly with the stock car ins. cluster's rev counter.
I wouldn't be too sure that it'd generate a proper signal for the shift light seeing as the amp. is also connected to the coil, try it out anyhow.
Let me know if it goes ok.
