Time
Keep them separate. Keep fuse a close to the battery as possible within 7 inches recommended. Do not solder the ends. Use the proper marine grade tinned wire.
Use the proper terminal and connectors. Do it once and do it right. You don't want it to fail at the wrong time. If you use the new style plugs you can make a bracket from some scrap aluminum and cut the 1 1/8 inch hole to fit the plug.
You can then mount the bracket to your boat. Did this to my boat and it works great.

PLEASE READ THROUGH ALL INSTRUCTIONS PRIOR TO
INSTALLATION.
Required for Installation and NOT included with this kit:
• 30 amp fuse with fuse holder
Overcurrent Protection
The wiring between the battery and the receptacle must have proper
overcurrent protection in the form of an inline 30-amp fuse. Position the
overcurrent protection within 7” of the battery.
Wire Gauge
Use good quality marine grade tinned electrical wire to bring power to your
downrigger. To determine the correct gauge of wire, measure the “wire run
length” which is the distance from the positive (+) power source connection,
to your downrigger and back to the negative (-) power source connection.
For wire run lengths up to 25 feet use minimum 12 Ga. wire, for runs of 25
– 40 feet use 10 Ga. wire. Wire smaller than the recommended gauge will
not carry sufficient power to operate your downrigger at its rated speed and
power, it will run noticeably slower.
The downrigger should always be unplugged when not in use.
Receptacle Installation & Wiring
It is important that the receptacle is wired to match how the plug is wired. The
terminals marked “1” and “2” on the receptacle mate with the corresponding
terminals marked “1” and “2” on the plug.
1. Mounting the receptacle requires a 1 1/8” hole to be drilled. Select
a location where the boats structure will not be weakened. Also,
mount on a vertical surface to lessen the amount of water that can
enter the receptacle.
2. Using the template on page 6, mark and drill the required holes.
3. Slide the rubber receptacle boot onto the wire. Strip the wire
insulation back ½” to expose clean bare wire. Do NOT solder the
ends of the wires.
4. Feed the wire from the back, through the 1 1/8” hole. Insert the
negative (-) wire into terminal “1” and the fused positive (+) wire
into terminal “2” and tighten both terminal screws. Make certain
there is no wire insulation inside the terminals, and there are no
stray wire strands outside the terminals. Do not overtighten!
5. Mount the receptacle. Ensure the drain hole is facing down.
6. Push the rubber receptacle boot onto the receptacle from the
backside.
