good day lads, i was wondering if any of you have a manual for a mercury marine PCM0309M, the fuel relay driver is fault i presume, ecu was sent to me, i need a manual to track down what pin it is, i have been testing pin 23 on connector A but i need to know what to trace back before removing components on this PCB, hoping someone could share experience. i found KTAG supports this ECU, but only shows power and gnd wire locations, hoping someone can be of assistance.
