Hello, I recently purchased a 1993 120hp Evinrude the previous owner was not using the vro system hence the was an old style fuel pump. I purchased a new vro2 pump and tank assembly. My problem is the new pump has a 4 wire plug on it and I have no wiring diagram. I purchased a seloc online manual for this engine went to the wiring diagrams and guess what the power head wiring diagram does not show the vro wiring. Can anyone point me in the right direction as to where I can view a wiring diagram for the vro2 system with a 4 wire pump please? Thank you for your time and attention. Robert
