harness extenstion needed

[Ted655]

1987 115 2cyl.
I need a longer wiring harness. Ineed 22'
I'm switching from side mount to top mount and moving the helm forward and to center.
There is supposed to be a "rigging guide" on this site but I can't navigate it at all.
Any help is appreciated. Thanks, Ted
