Okay, so I have my Megasqurt 2 V3.0 all done and ready to go on the car (Porsche 944 S2). The car has a Bosch 55 pin style harness connector so I got the adapter from DIY autotune and I am trying to go from the DB37 to the Bosch connector. I have the Bosch's pinout, but I am not totally sire on the DB 37's. I looked online and there are so many different ways to wire things it seems like. Will somebody please point me in the right direction?

The basics on MS2 are pretty well all hard wired to the DB37 via the PCB. Power, tach input, injectors, TPS. CTS, ATS, etc. Choices happen for things like idle speed control. Only you know how you've configured that side of things.
If you wish a plug and play unit, where you can swap between original ECU and MS, and aren't good at reading schematics, an MS PNP may be a better option.

Thank you fo your reply, I don't think I made much sense though. I am looking for what each pin on the DB37 does. like what pin 1 does, pin 2 does, and so on.
Thank you for helping me! - Chris

I think that most of what you're looking for (pinouts, schematics, etc) can be found in the various MS manuals.
Hope that helps.......
