Yamaha Dual Staion, Dual Engine controls wiring Diagram needed.

[pescador 17]

Does anybody have an installation manual or wiring diagram for Yamaha dual station controls for dual engine engines. I have a set of used controls plus harness gauges and key switch. I did not take it out but everything is supposed to be there. I'm trying to make sense of all of the harnesses, and connections. The Control is a Yamaha 704 and I am connecting to two 85HP 2006 Yamaha outboard motors.
The cabling from the motors are from controls 703, 10 pin, I need to figure out the cabling to combine the 704 Dual Control to 703 cabling.
Any plans/diagrams of wiring of the 704 and 703 controls would help me immensely.

Thanks in advance for your help. (charliebigfishNOSPAM@yahoo.com)

the cables for the 704 and 705 are the same.
there are no good diagrams of the yamaha duel station rigging.
the rigging guide of about 2008 is fair.
