Okay so I am looking at the wiring diagram for the MS2 V3 board:
It shows grounds coming from pins (8,9,10,11,18,and19) according to the mega manual, the IAT, Collant, and TPS should be ground to pin 19, and the rest should be grounded to the chasis in the same place.
I have a DIYAUTOtune.com MS harness and I pulled it apart, it has 6 ground wires: pins (1,2,3,11,12,13) and what looks like the shielding for the ignitionl wire in pin 18...
I am getting confused. On the DIYAUTOtune harness they also have pins 1,2,3 connected to one main ground wire, and pins 11,12,13 the same, so at the end of the harness there only appears to be the two ground wires. What am I missing? Do I need to rewire the DB connector for my MS?
Should I just go ahead and run a wire to pin 19 with the grounds for the IAT, Coolant, and TPS? Or should I just connect all the sensors to the two ground wires on my harness?
