Remote start tach wire

So instead of me putting another wire running through my engine bay where can I find the tach wire inside of the car

Best is to run the lead into the engine bay and wire it to one of the injector control leads.

You should be able to get a tech signal at the ECU/ECM. 94

Cool I just went and wired it straight to the distributor cause I couldn’t find the tach wire inside of the car but thanks
