ONAN 5500 Installation. The wires are labeled on the harness as follows on a typical ONAN 8-pin wiring harness

Here are typical installation guidelines for an ONAN 5500 Gas/Diesel/Propane with a 8-pin generator wiring harness.

Note: For action 7 you will have to buy 14-gauge electric cable for the run from our ShorePower Monitor to your transfer switch.


Turn-off your generator AC circuit breakers in order to avoid interruption of coast energy solution during testing and installation of ShorePower Monitor.


Determine the following 4 cables on your own generator wiring harness.

Make use of a tape or label to mark each cable which means you won’t forget which wire is which.

  • A – Ground – Brown
  • B – Stop – Green
  • C – Begin – Red
  • E – Run – Orange

On a normal ONAN 10-pin wiring harness the cables are labeled in the harness the following

  • A – Ground
  • C – Begin
  • E – Stop
  • F – Run

NOTE: The pin connections above are typical ONAN connections. Not absolutely all ONAN generators have actually the exact same generator wiring harness connections as some might have been changed by the dealer or RV maker. Make sure you have actually precisely identified the 4 cables precisely before proceeding with step three.


Connect one Posi-Tap to each regarding the 4 cables identified in step two.


Result in the connection through the ShorePower track to your Posi-Taps (wiring harness) according to the wiring diagram provided.

  • Green cable to E AVOID
  • Red cable to C BEGIN
  • Brown cable to A GROUND
  • Orange cable to FRUN

Be sure to connect the wires that are correct the wiring harness once we utilize red-colored cables more often than once.

On our installation picture we utilized white cables to expand to your harness as a result of location of y our product. The closer the installation of y our product to your wiring harness will help you to utilize the provided wire that is 4-foot we offer.


  • Link the red wire from the ShorePower Monitor (I3) to at least one part associated with the enable switch utilizing the provided Posi-Lock or a crimp connector.
  • Connect the 2nd red wire (supplied in the zip-lock case) to another part associated with the enable switch. One other end fruitful link with this wire that is red ultimately get in touch to your good battery pack terminal.


  • Connect the red cable through the enable switch additionally the red cable from (L+) in the ShorePower track to your +12 VDC (good battery terminal).
  • Link the black colored cable (M) regarding the ShorePower track to ground (any steel on the RV).


Through the ShorePower Monitor Power Converter ( See wiring diagram B – Transfer Switch Connection):

You will need 14-gauge stranded electrical wire for the run from our device to your transfer switch.

  • Connect (L) on our MeanWell Power Converter to 1 region of the 110 Volts in the transfer switch.
  • Link the (N) on our MeanWell Power Converter into the center connection (common) regarding the transfer switch


The ShorePower track & the MeanWell Power Converter should both have their light that is green ON if most of the cables, like the cables towards the transfer switch, have already been properly linked. .

  • To evaluate the machine switch on the ALLOW Switch and disconnect from coast energy. The green light on the MeanWell is certainly going down and in around 20 seconds our product will auto-start your generator.
  • Let generator run for around a moment then re-connect to shore energy and our product will automatically shut-off your generator in more or less seconds that are 10-12. The light that is green the MeanWell should come right right back on.

SIGNIFICANT NOTE: switching the ALLOW CHANGE On or OFF will not impact the light that is green the ShorePower track or MeanWell. Those two light will always be on IF the ShorePower Monitor is properly connect and you have shore power. The ALLOW CHANGE just allows or disables monitoring.

This is just what a set-up that is typical seem like as soon as it is finished. You will see other client installation photos by clicking right right here.
