Just upgraded my Aeroforce from the older version to the newer version. The wiring looks exactly the same as the old one and I have it hooked up the exact same way as before only now, when it is plugged into the OBD2 it stays on. I have my IC pump and both WB and aero all hooked up on the same switched source (so if the gauges are not on, neither is the pump). The pump stays off when plugged into the OBD2 and both WB and aero turn/stay on...
So if I can try to make an Image...
Aeroforce- OBD connector to back of gauge... red wire from the analog to switched 12v and both analogs capped.
WB (AEM EUGO to be exact)- red to same switched power as Aero, black to ground and white to HPtuners 1, HPtuners 5 to same ground...
Pump- pump/aero/WB to switch and then switch to fuse box.
Also, when the OBD2 for the Aero is not plugged in, the switch still turns the WB on and off like normal.
