DF50 - how to wire trim, tacho and trim gauge?

[Netics]

Hi!

I have the DF50 2001 model, and bought the:

Suzuki Side Mount Controle Box (67200- 93j03)
Suzuki White Tachometer (34200-93j11)
Suzuki White Trim Gauge (34800-93j11)
Suzuki wire harness (36620-93j01)

All the components fit the wiring harness, but it wont fit the engine. How can i fit this to my engine? Is there a convertion cable that I can use?

Thank you.

I now bought the adapter so it fits, but there are so many wires on the tachometer and the trim gauge that are the same colour, where do they go?
