Yamaha side mount remote control wiring (4)

[Rrichterr]

Hi Guys,

Repowering my boat with a 2007 Yamaha F115 4-stroke with a new control box (703) that is replacing a 1996 Mariner 135 2stroke and it’s associated Mercury side mount control box

Can anyone identify the wire assignments for the 4 wire pigtail that exits this new control box (see pic) ?

Has anyone done this conversion and figured out how to tie these 4 wires into the Mercury pigtail that had a 5 pin plug. Going to the dash?

Any help appreciated. Thx

Red is battery power.
Yellow is key on battery power.
Black is battery ground.
Green is the tachometer signal.

Here is the way that Yamaha does it.

Thank you sir. Will attempt to feed these to the original harness to get some of gushes working.
