Hey guys I'm new to tuning and the forum here. I ordered the Pro link set for my MPVI2 unit and have an AEM X-series wideband. I'm wanting to wire the AEM to the pro link so that I can log wideband data from cars that don't run on a CANBUS system. I was thinking about taking the pin out of the #3 pin and putting it in the #9 pin for a 5v signal and wiring it to one of the analog inputs on the pro link, but I'm not sure where to wire the ground for the pro link. Do I just wire it into the ground wire on the back of the AEM?
