ECM 555 hookup

skidrow

I have recently purchased a mercruiser scan tool for my 04 fv270.. This has the ECM 555....I purchased the connector cable for this but I can't find any cable to connect to..looked all around the ECM.... Anyone know where it is?

The connector should be in the front part of the engine on top and it should have a label to identify it. Not necessary close to the ECM.

THanks...I'll have another look around.....what is the label;s name?

frenchship

On mine it says diagnostic and it has four wires .

Found it..mine says diags/depth sounder......thanks for the help.

The mercruiser handheld ....by rinda technologies.

I have the same really good tools. It already pay for itself many times.
