Hello!

Bought a used Zero Effort control today (single enginge with trim switch) and attached to the shifter its a harness of 5 cables.

Two of them Yellow and Yellow/Red comes from the Shift handle and Red/Blue/Green from the Throttle Handle

Im gonna replace my ultraflex handle with a addon trimswitch from Rex marine.

What cables do i need and where to connect them?

Thanks
David

Also adding that the controls been used on an outboard before so maybe some cables are for some specific function on outboard engines?

Red=power to trim switch
Green= down trim
Blue=up trim

Yellow and Red/Yellow are for neutral safety switch.

Just put male bullet connectors on all of them and then female bullet connectors on the wires they connect to.
