External 1990 Tach Adapter


This adapter can be installed on the ECU harness wire #109, and make the tach pulses of your 1990 DSM compatable with any 1991-94 ECU! If you also swap pins 6&14 of the ECU, the 1991+ ECU will be plug-n-play in any 1990 Turbo DSM! Check out my White Paper for installation instructions.
