Has anyone found an easier tach wire than what the Astrochart has? Removing the two tanks and attaching behind on that plugs is a real pain in the butt! Adds so much to the install time.

Tach wire is BLACK (AC) @ PCM Pin # 26.*

*PCM located on passenger side of engine compartment. Black connector in middle.*

There are 3 wires at each of the coils on the engine. Pink, Black and a third wire which can be used for a tach reference.
