Default Yamaha F225 Wiring?

I replaced my Yamaha F225 with another, used F225 of approximately the same vintage. The wiring is different from my original motor, and this has me scratching my head.

Here are the plugs that come from the gauges on my boat:

Here is one of the plugs on the outboard:

In addition to the wires having different colors, the plugs coming from the gauges and the plugs on the outboard are both female.

More info:
Original motor is an F225TXR, 7/05 manufacture date, with N2K.

Replacement motor is an F225TXRD, 2/05 manufacture date, with N2K.

My controls are dual 703 side mount controls. The replacement motor came off a boat rigged with 704 dual binnacle controls. From what I've gathered, these controls use different wiring harnesses, but they should both be compatible with the outboard, right?

How do I make this work?

There should be only two connections you use, the large black plug and the female plug with the pink wires. The female plug from the harness is not used on an 05. The male end from the harness should be plugged in to the female plug (pink wires) on the engine side.

The male plug on my harness has 4 wires, it looks like yours only has 2. Plug it in a see if everything works.

That worked, thanks!

Full sea trial in store for this weekend.

I don't seem to have any trim indication on the Yamaha gauge, but I haven't fiddled with it much, either. I take a closer look before I go out this weekend.

the "trim and oil harness" which connects to the white-ish engine connector -
usually has 4 wires - but only does three things on your engine
I am baffled that your photos seem to show that there are only two wires

the green illuminates the "low oil pressure" indicator on the tach
the green/red illuminates the "high temp" indicator on the tach

I would expect to see on that connector a blue/white (which does nothing)
and a red/white - which is the trim indication
like so:
