im installing an AIM dash in a dc5 and i have only enough wiring in the car to make it run, on what i believe is a not-so-stock ecu. motor is a k20a red valve cover.
I need to know which wire in the engine bay to pull tach signal from. pictures if you can, in case the wiring is routed differently on this car.

also, what should i set the redline at?

this is a race car, and i am not well versed in dc5 (yet)

-thanks,
matt
