Spent two hours cutting tie wraps off loom installing transducer wire in loom then rewrapping it

back.Now for the question,i have a electrical panal with three switches with a fuse under each.

One is aerator,bilge lights,to the side i have a factory cig lighter with red,blk feed ing off the light

wires.Can i splice into the lighter power or just remove the bullet connectors and send it directly

to the depthfinder,i touched the wires and it will come on.

What are you asking?

You can wire directly off the hot side of your panel, However be careful not to overload the circuit. This can and will cause costly damage to your fishfinder if not done properly.

Be sure to use that little inline fuse.

I plan on soldering the inline fuse before the tap if thats the route i go.
