Just for those who are interested, I installed a DET3 in piggyback mode on an early 3000gt/GTO Twin Turbo.


DET3 Function ECU
Pin 1 12V Pin 12
Pin 11 Ground Pin 13
Pin 3 +10 MAF Input Pin 70 (Harness/Sensor Side)
Pin 7 MAF Output Pin 70 (ECU side)
Pin 8 + 9 Crank Input Pin 69 (Harness/Sensor Side)
Pin 6 Crank Output Pin 69 (ECU Side).

The only thing I'm notsure on is Freq Min 10, and Base Unit 4.
The car did run pretty smooth after install, so it should be fine.
