had a power fc intalled, now i am going for aem ems. i was checking out the wires and notice that the ( tdc ref trigger) wire is missing, the car startet and drive with the powerfc, but with the aem ems will not start, need this signal for the engine to do so, where does the "tdc ref trigger" signal comes from? any diagram? appreciate some help so i can built this wire from the sensor onto the aem ems pin...

best regards

No idea about a TDC ref trigger but the FD does use a crank sensor located at the front of the motor.
