hi boaters,
i am sure some of you have installed a newer motor to an old boat...

so, my issue....
i purchased the quicksilver harness assembly adapter to go from the new motor to the old boats 8pin connector plug...
I have things connected but not starting so I am missing something.
the starter will try to engage the flywheel but does not turn the motor over...
from the adapter harness on the motor side...there are 4 wires outside the screw on plug...
brown with white stripe...…………..for?
tan...……… I think temp gauge
the blue and green I have connected to the trim up and down which works.

does this brown and white wire have to connect to something?

on my old 8 pin plug side, there is a lone purple wire I am wondering where it may go...

any ideas and help is appreciated...
as I said, I am sure others have re-powered an old boat.
