So these are the diagrams I've been using to wire this up so far:
And this shows the ACTUAL pinout of the premade DB37 connector I have. It apparently has changed since the above diagram was made.
The internal mods to the MS 3.57 that I have done are:
1K ohm resistor between JS10 and PAD7
470 ohm resistor from PAD7 to the +5V hole
0.1microfarad Capacitor between JS8 and GND
470 ohm resistor across the two terminals of R57
So, where I'm at right now is, since the grounds are different between the two DB37 connectors I wasn't sure exactly how to hook them up, and I wasn't sure if it really mattered where I hook them up. Right now I have pins 17, 18, and 19 from the DB37 hooked up to 2A on the harness, pins 15 and 16 hooked up to 2B, and the black/white sensor ground wire from PIN 7 hooked up to 2C.
I don't have spark output B hooked up yet because it now comes out on the DB15 connector. I don't see the Gn/W wire on the DB37 for the fans so I'm guessing that now comes out on the DB15 connector as well but I do not know where? Lastly, the only other thing I don't have hooked up yet is the crank in for Pin 2E, the wire is supposed to be the twisted shielded wire, but this wire is actually a black and white wire twisted together so I'm not sure which of the two or if both get hooked up to the connector. Also, I'm assuming that the bare shield wire in there is NOT supposed to be hooked up to a ground or anything, right?
I appreciate any help! I was able to load firmware to the MS yesterday finally but now I have to fix my laptop because for some reason it crashes every time I load tunerstudio except in Safe mode, but it won't communicate through the COM port when it's in safe mode
the problems never end...
