The next step in installing your fish finder would be to route all the cablefrom the transducer to the control head, and from the battery to the control head. This is an important step in the cosmetic and professional appearance of the job. You want the cables to be hidden as much as you possibly can.

     There are a few ways to route these cables. 1. you can route them over the transom, and 2. you can route them through the transom from the transducer.

     To mount the cables over the transom, you simply run the cable over the transom and secure it with cable clamps. Any holes you drill should be sealed with silicon sealant like the same method as the Transom mounting holes were sealed. Run the cables along conduit or under rims to hide the cable and secure it along the way with cable clamps until you reach all the way to the control head.

     To mount the cable through the transom you must drill a 5/8" hole to run the cable through. MAKE SURE THE HOLE IS ABOVE THE WATER LINE. Run the cable to the control head the same way you did for the over the transom mount. When you have excess cable, roll it up neatly and store out of site and out of the way.

     Now the cable for the power source must be run to the control head. You can connect the wire directly but it is better and more safe to install an in line fuse between the power source and the control head. Run the wires hidden as you did with the transducer cable. Remember when hooking up the power source that the black is negative and the red wire is positive. To insure the best quality performance out of your fish finder, it is best to use a power source for the fish finder that is JUST for the fish finder. This reduces interference with the unit. You have  noe completed the 2nd step of the installation and you are ready to move on to step three which is to mount the control head itself.
