EDIS wiring with 3.57??

Greetings,
I just received a new, complete DIY 3.57smd unit. I noticed that the external wiring diagram, titled V3.0/V3.57, that came with it is slightly different than the V3.0 I previously used. In the newer version the VR sensor has + going to pin 24, - going to pin 1 and the shield going to pin 2. The previous version of the diagram has sensor + going to pin 24, sensor - going to pin2 and no shield shown and nothing hooked to pin 1. Has the circuit changed?

Also, does anyone have a complete wiring diagram that shows the EDIS (crank) sensor, hooked to the EDIS ignition system and m'squirt, using the latest Megasquirt 3.57. If PIP (pin 1/EDIS) goes to p24 of the m'squirt, and saw (pin 3 /EDIS) goes to pin 36 of the M'squirt and the crank sensor goes to pins 5&6 of the EDIS...............what is hooked up to pins 1&2 of the m'squirt.................where does the m'squirt get the tach signal, etc.

Regards,

No, we've merely added an extra ground to our harness for VR sensors.

Nothing needs to be hooked to MegaSquirt pins 1 and 2; they're grounds. The MegaSquirt gets its tach signal from PIP.
