Mercury vessel view

[Dom140]

Hi I've bought mercury vessel view to use on my 2006 1900 SR3 with a 5.0MPI.

I'm struggling to locate the plug in the engine bay that connects to the vessel view module. Its been suggested yellow or purple plug and I can't find it anywhere.

Any suggestions would be great. I assumed being 2006 and an MPI engine that it would be plug and play.

Many thanks
