Im installing a monsoon 335 in my 21ft carrera. The motor came complete with engine harness. It jas a 10 pin connector off the delphi mefi4 ecm. Im having trouble finding the pin inputs/outputs to make the harness and I noticed a crank sensor installed with no plug. im assuming its needed for injection timing. I found a purple and pink wire cut near the alt. Are they the ckp wires? Indmar has no info for the consumer. Only dealer
