• Heat Gun
• Drill
• 1-¾” Hole Saw
• 1/8″ Drill Bit
• Phillips Screw Driver

MOUNTING CONSIDERATIONS

Before installing your Trolling Motor Plug and Receptacle, consider the following:

1. The mounting surface needs to have a flat area no less than 3-¼” wide x 2-½ inches high. Use the Face Plate (Item #2) to check for clearance at the desired mounting location.
   WARNING
   Make sure the power source is disconnected or, if controlled by a switch, turned OFF before beginning installation of the Plug Receptacle. Failure to remove power from the Boat Wires could cause electric shock.
   NOTICE: If uncomfortable making this installation, we recommend having the Motor Plug and Receptacle installed by a qualified marine installer.
   WARNING Do not tin any wires with this installation. Tinned wires could cause the connection to loosen over time, creating an improper connection. Improper connections could cause ae electrical short or extreme fire danger. Follow the installation instructions provided to avoid product failure and injury.

2. Make sure the area under the mounting location is clear to drill holes and that installation hardware will not damage existing components or wiring below the mounting surface.

3. Make sure that the trolling motor Power Leads and the Boat Wires are not connected to a power source before beginning installation.

4. Test that the Boat Wires can reach the intended mounting location to be attached to the Plug Receptacle. Also, check that the Trolling Motor Lead Wires can reach the Plug Assembly wires and that there is enough slack that the plug can be both plugged in and unplugged at the intended location. All wires should not only reach but also have extra slack to allow for ease of installation or repairs and relieve tension on the final installation. If the wires are not adequate in length, select another location.

5. Determine if the mounting location will work when the Plug Assembly is plugged into the Plug Receptacle. Check for clearance
   that will be required for the cords exiting and entering on both sides of the installation. Allow for space for the cords to exist and accommodate plugging and unplugging the plug as needed.

INSTALLATION

Trolling Motor Plug and Receptacle Installation

• Review the Mounting Considerations and determine  an acceptable Mounting Location.
  WARNING Make sure the power source is disconnected or, if controlled by a switch, turned OFF before beginning installation of the Plug Receptacle. Failure to remove power from the Boat Wires could cause electric shock.

• Once an acceptable Mounting Location is selected, remove any power leading to the Boat Wires. Use a Drill with a 1-¾” Hole Saw to drill a hole through the selected location.

• With the hole drilled, locate the Boat Wires that the plug will be connected to. The wires may need to be trimmed and stripped. Use a Wire Cutter to cut the wires to remove any terminals or covers that may be in place.
  NOTICE: For ease of installation, it is recommended to stagger the ends of the wires by 1-¼”. Make the Negative (-) Boat Wire the shorter wire of the two. Staggering the length of the wires will help with the installation of the hardware used to connect the wires later in the installation.
  NOTICE: The ends of the Boat Wires may have any sort of electrical connector that should be removed.

• With a Wire Stripper, remove the protective covering on the wires. It is recommended to remove ½” to ¾” of the protective covering to expose the wires. Use a Ruler to measure this distance if necessary. If the Positive (+) and Negative (-) Boat Wires are fused together, split them so they are separated for a minimum of 2-½” from the end of the shortest wire.

• Take the Boat Wires and fish them through the 1-¾” hole that was cut in the Mounting Location. The wires should pass from the back so that the newly trimmed ends exit the front of the hole.

• The Boat Wires that were stripped will be covered with a Ferrule (Items #20, 22, 24, 26, 28 or 30) to contain the wire strands. Take two Ferrules and place one at the end of each wire, encasing all of the wire strands.
  NOTICE: The Ferrule selected will depend on the boat wire size. The two extra 8 AWG Ferrules (Item #28) may only be needed if the Plug Receptacle wires need to be trimmed or recapped.

• With the wires out the front of the Mounting Location, take one of the two-inch Shrink Tubes (Item #16) and place one on the end of the longer Positive (+) Boat Wire.

• Take one Splicer (Item #18) and place it on the end of the Positive (+) Boat Wire. The Splicer is secured to the Boat Wire over the Ferrule. Secure the Splicer by tightening the Set Screw with the 3/16″ Allen Wrench (Item # 34) to 20 in-lbs.
  NOTICE: Boat Wire sizes vary, so it may be necessary to use a different sized Ferrule.
  

• The other Splicer and Shrink Tube should be added to the Plug Receptacle so it can be attached to the Boat Wires. Take the Plug Receptacle (Item #B) and place one Shrink Tube (Item #16), followed by one Splicer (Item #18) on the end of the black Negative (-) Wire of the Plug Receptacle. Secure the Splicer by tightening the Set Screw with the 3/16″ Allen Wrench (Item #34) to 20 in-lbs.
  NOTICE: The positive (+) and negative (-) wires on the Plug Receptacle should have Ferrules already applied.

• Take the Plug Receptacle and identify the red Positive (+) Wire on the Plug Receptacle and align it with the Positive (+) Boat Wire. Insert it into the Splicer at the end of the Positive (+) Boat Wire. Take the black Negative (-) Wire from the Plug Receptacle and align it with the Negative (-) Boat Wire. Insert it in the Splicer at the end of the black Negative (-) Wire of the Plug Receptacle. Secure the Set Screw of both Splicers with the 3/16” Allen Wrench to 20 in-lbs.

• Once the Splicers are secure on both wires, take the Shrink Tubes and slide them over the Splicers. The Shrink Tube should be centered over the Splicer and completely cover the wire connections.

• When satisfied with the position, secure the Shrink Tubes in place with a Heat Gun. Ensure that there is no opening around the Shrink Tubes when heated. Push the wires and the Plug Receptacle into the drilled hole until the Plug Receptacle sits against the mounting surface.

NOTICE: The Shrink Tubes are meant to water proof the connection between the Plug Receptacle and the Boat Wires. Make sure there are no gaps around the wires that would allow water to reach the connection.

• The Face Plate (Item #2) is keyed with the Plug Receptacle. Turn the Face Plate over and notice the notches along the Inner Circle. These notches are keyed with the outer edge of the Plug Receptacle when it sits flush on the mounting surface. This allows the Face Plate or Plug Receptacle to be rotated in 45 degree increments.
  NOTICE: Tethering the Dust Cap to the Face Plate during installation is optional. The Dust Cap can be stowed away when the plug is in use and should be replaced for storage or transport.

• On the back side of the Face Plate, there is also
  a hook to attach the Dust Cover (Item #C). Determine if the Dust Cover will hang to the right or the left and turn the hook on the Face Plate to the appropriate direction.

• Flip the Face Plate so the keys on the Inner Circle are towards the mounting surface and place it over the Plug Receptacle. It should be seated on the mounting surface.

• Take the Plug Assembly (Item #A) and plug it into the Plug Receptacle. The Plug Assembly and Plug Receptacle are also keyed with each other. Orientate the Plug Assembly and Plug Receptacle so they can be fully pushed together. The Threaded Collar on the Plug Assembly does not have to be tightened.

NOTICE: Use the Dust Cap when the plug is not in use to insure optimal water-tight protection to electrical contacts.

• Turn the entire assembly to the right or left until the Cord from the Plug Assembly is in an acceptable location. Check for clearance of other items on the mounting surface and if the cord will interfere with the operation of anything in the area.
  NOTICE: Make sure the location also allows for the Plug to be connected and disconnected. Then the Locking Collar can be secured once the Plug is in use.

• Once in an acceptable location, take a pen or marking tool and mark the mounting surface in each of the screw holes on the Face Plate. Make note of the orientation of the Plug for correct placement in the next steps of installation. With the locations marked, remove the Plug Assembly from the Plug Receptacle and set it aside.

• Lift the Plug Receptacle, Face Plate and wires forward out of the drilled hole and leave it hang out of the way. Take a Drill with an 1/8″ Drill Bit and drill pilot holes into the Mounting Surface on the Marked Locations.

• With pilot holes drilled, push the wires, Face Plate and Plug Receptacle back in place on the Mounting Surface.

• Double check the location of the Hook on the back side of the Face Plate. The Loop in the cable of the Dust Cover should be placed in the Hook of the Face Plate. Once secure, push the Face Plate all the way back against the mounting surface. Ensure the Plug Receptacle is positioned as previously noted.

• Realign the drilled pilot holes with the screw holes on the Face Plate. Secure the Face Plate with four #8-18 x 1-¼ Screws (Item #32) using a Phillips Screw Driver.

• Locate the Power Leads for the trolling motor. Turn the power to the motor “off” and remove the motor Power Leads from any power source.

• The wires may need to be trimmed and stripped. Make sure that the wires are long enough to reach the installation location. Use a Wire Cutter to cut the wires to remove any terminals or covers that may be in place. Cut the wires so that the ends of the wires are staggered, and the Negative (-) Power Lead is approximately 1-¼” longer than the Positive (+) Power Lead.

• With a Wire Stripper remove the protective covering on the wires. It is recommended to remove ½” to ¾” of the protective covering to expose the wires. Use a Ruler to measure this distance if necessary. If the Positive (+) Power Lead and Negative (-) Power Lead of the Trolling Motor Wires are fused together, split them so they are separated by a minimum of 2-½” from the end of the shortest wire.
  WAR
  NING Make sure that the trolling motor wires are not connected to a power source. Failure to remove power could cause electric shock.
  

• Both the Positive (+) Power Lead and Negative (-) Power Lead of the Trolling Motor Wires should be covered with a Ferrule. Take two 10 AWG or 8 AWG Ferrules (Item #10) or (Item #12) and place one on the end of each of the motor wires. With the Ferrules placed, take the Splice Cover (Item #4) and thread both the Positive (+) and Negative (-) Power Lead of the Trolling Motor Wires through it.
  NOTICE: The 10 AWG Ferrules are the smallest in the provided hardware. The two extra 8 AWG Ferrules (Item #10) may only be needed if the Plug Assembly wires need to be trimmed or recapped. Wire sizes vary, so it may be necessary to use a different sized Ferrule.

• Take one of the two-inch Shrink Tubes (Items #6) and place one on the end of the longer Negative (-) Power Lead of the Trolling Motor Wire. Take one Splicer (Item #8) and place it on the end of the same wire. Secure the Splicer by tightening the Set Screw with a 3/32″ Allen Wrench (Item #14) to 20 in-lbs.

• The other Splicer and Shrink Tube should be added to the Plug Receptacle so it can be attached to the Boat Wires. Take the Plug Receptacle (Item #B) and place one Shrink Tube (Item #6), followed by one Splicer
  (Item #8) on the end of the black Negative (-) Wire of the Plug Receptacle. Secure the Splicer by tightening the Set Screw with a 3/32″ Allen Wrench (Item

  14) to 20 in-lbs.

• Take the Plug Assembly and identify the red Positive (+) Power Lead on the Plug Assembly and align
  it with the Positive (+) Power Lead on the Trolling Motor Wires. Insert it into the Splicer at the end of the Positive (+) Lead Wire from the Plug Assembly. Take the black Negative (-) Power Lead from the Plug Assembly and align it with the Negative (-) Power Lead from the Trolling Motor Wires. Insert it in the Splicer at the end of the black Negative (-) Power Lead of from the Trolling Motor Wires. Secure the Set Screw of both Splicers with the 3/32” Allen Wrench.

• Once the Splicers are secure on both wires, take the Shrink Tubes and slide them over the Splicers. The Shrink Tubes should be centered over the Splicers and completely cover the wire connections.
  NOTICE: The Shrink Tubes are meant to water proof the connection between the Plug Assembly and the Trolling Motor Wires. Make sure there are no gaps around the wires that would allow water to reach the connection.

• When satisfied with the position, secure the Shrink Tubes in place with a Heat Gun. Then slide the Splice Cover over the Shrink Tubes to complete the installation.
  NOTICE: When disconnecting the Plug Assembly from the Receptacle, be sure to install and tighten the Dust Cap. This will prevent water or debris intrusion.

NOTICE: When connecting the Plug Assembly to the Receptacle, be sure to tighten the Threaded Collar to ensure a proper water-tight seal. A water-tight seal protects electrical contacts. Failure to tighten the Threaded Collar could result in water intrusion.
