got my ducers installed and ready to mount and power on new unit. opened the package and there are two cords out of the part that connects to the unit. one is for power and other is for 0183. none of the wires has connectors on them and I am not sure how to proceed. several questions:

1. do I need a separate battery for the unit, or can I hook it to my starting battery or my trolling motor battery - both are 12V - I often fish for 10-12 hours at a time, with trolling motor used quite a large part of that time (say 2/4 hours on and off).

2. the pin connector that connects to the unit's power socket has two cords. One (10-18VDC fuse ATC 3) has a red, a black, and a yellow wire. I assume I just crimp a connector on each (after connecting the supplied fuse to the red) and hook red to positive and black to negative. what the heck do I do with the yellow one?

3. the other (NMEA 0183) has blue, green, orange, yellow, and a ground wire. do I crimp these individually, some together(transmit: yellow/blue) (receive: Orange/green), or what? what do I connect them to. what is the ground for?

Sorry for so many questions, but don't want to blow up my new unit out of ignorance on my part.

it's a Gen 2 touch with side scan, if that matters.
