Control box question 703

What comes with the control box and what cables will I have to purchase seperate? This is for a new Yamaha 25 2stroke elec start, no gauges, no tilt and trim. Thanks in advance!

703-48230-15-10 control box comes with key switch and 16ft 7 pin harness.
Will need 2 MAR-CABLE-xx-SC(replace xx with length cables needed) control cables.

How hard is it to hook the mar-cable up? Does the cable come with instructions to hook up both ends?

Just thread cable end on about 8mm and cables are held on with E-Clips.
