ok take a pm 5 for example. there are three connectors going to it. how do you decide which is connector A,B,C
they aren't marked and I don't have a helms manual. I know I'm looking for pin C16 to connect an air/fuel ratio gage to, for the time being I'm tapped into the 02 sensor in the engine bay, but would like to connect to the ecu.
thanks in advance
