Removing Dual Control and Wiring 96 225 twins

[Loyal to none]

Sold tower off boat. I am removing the upper 704 control, gages and the dual contol boxs and wiring harness. Is there a wiring diagram that will show the connections for the engines main harness to the Ing. switches and gages and to 704 control at the consol. I am also rigging new throttle and shift cables from each engine to the new 704 control. I have removed the upper and lower harness for having the dual units but the wire colors in the manual are not readable.
Thanks
Mitch
