Installation instructions

  1. Remove old inlet’s four mounting screws and remove the inlet from the *boat. Image 1
  2. If the old inlet has a rear safety enclosure, loosen the strain relief clamp and remove.
  3. Loosen the screws on the side to disconnect the inlet from the *boats internal wiring and remove the old inlet. Image 2
  4. Examine the *boats internal wiring. Make sure the wire is in good condition, a clean and bright copper color. If necessary, cut back until clean wire is found.
  5. Test your new SmartPlug for proper fit and alignment of screw holes. (On some installations, you may have to modify the hole in your *boat to accept the new plug. Please use the enclosed rear mounting gasket as template if necessary. Image 4 or Click here for a printable mounting template.)
  6. Strip the wire insulation back 5/8”. Do not solder the ends of the wire.
  7. Place the rear mounting gasket included in the packaging on to the back of the inlet. Images 3 & 4
  8. Back off the wire terminal screw clamps on the back of the inlet housing. Twist bare copper wires into a tight and straight formation. Insert the bare wires into the corresponding color-coded terminals. Insert wire until insulation butts up against the plastic of the internal connection. Tighten the screw clamp after each wire is inserted. Make certain there is no insulation inside the terminal clamp. Image 5
