With a 6mm drill bit, drill the first two holes where the m6 x 40 Phillips pan head screws go through and then mark and drill through the 3rd hole where the cable will run through.
Install the cable through the 3d printed section as shown and push the plug down into the cavity.
This kayak is running both a sounder and light connected to a 17.5A FPV battery. I’m installing it by connecting the two positive (red) wires to the positive (red) wire on the FPV connector and then the same with the two negative wires (black) to the single negative (black) wire on the FPV connector. We use crimps and dual wall heat shrink to wire the kayaks to provide a sealed connection. Obviously, joining 2 wires to 1 wire even with glue lined heat shrink won’t keep the water out so you can epoxy the join also after just shrinking 1 end of the cables. The reason we use crimps is to avoid soldered connections as these can become weak with vibrations.
When joining your cables, its also great practice to stagger the joins. This ensures if they are rubbing together, there are no exposed connections that can touch each other.
When finishing up we always secure the cables with ties, so no weight is hanging on the joins.
I personally don’t run a switch because of the low current draw and leave the light on day and night, but you can add one in quickly. Just run the cable down to where you want to put the switch and then cut the positive wire and wire the switch inline. Here we have one of our dimmers and switch mounts for inside the Hobie hatch. We always have put our switches on the inside of the kayak so they are out of the elements.
Once the wiring is all done, you can install the fuse, plug in the light, and test it. This one has a high/low and off setting.
The last thing we provide is a blanking cap for the connector when not in use. We use gold plated terminals to have increased corrosion resistance, but we recommend to use this cap when not in use. Leave it in your car or somewhere dry when not using the light. The other thing that will increase how quickly it will corrode is if you leave the power connected to both your sounder and other outputs when not in use. We recommend always removing the battery.
