2005 F115 Multi-Function Tach Wiring

[On The Fly]

I've got a new 6Y5-8350T-82 tach, the 6Y5-83553-20 wire harness, and the 68F-82553-70 oil/trim gauge harness. Been all over the engine and found only 1 unused connector- female with 4 wires-p, pb,pb,pw. So, do I hook the male bl/w,r/w,g, g/r to this connector and forget about the other one and then hook up the green, blue, yellow, black at the tach? Doesn't seem to be any other option. The 83553 is already wired in the boat as is the main harness.
Thanks,
Roy
