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 the ONAN 5500 Gas/Diesel/Propane with a 8-pin generator wiring harness.

Note: For action 7 you’ll want to buy 14-gauge wire that is electrical the run from our ShorePower track to your transfer switch.


Turn-off your generator AC circuit breakers in order to avoid disruption of coast power solution during installation and assessment of ShorePower track.


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

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

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

The wires are labeled on the harness as follows on a typical ONAN 10-pin wiring harness

  • 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 generator that is same harness connections as some might have been changed because of the dealer or RV maker. Make certain you have actually precisely identified the 4 cables properly before proceeding with step three.


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


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

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

Remember to link the proper cables to the wiring harness once we utilize red-colored wires more often than once.

On our installation picture we utilized wires that are white expand into the harness because of location of y our product. The closer the installation of our device towards the wiring harness will assist you to utilize the provided wire that is 4-foot we offer.


  • Connect the red cable from the ShorePower Monitor (I3) to at least one region of the enable switch making use of the provided Posi-Lock or even a crimp connector.
  • Link the 2nd red cable (supplied in the zip-lock case) to another region of the switch that is enable. One other end of the wire that is red fundamentally link to your good battery pack terminal.


  • Link the red cable through the enable switch and also the red cable from (L+) from the ShorePower track to your +12 VDC (Positive 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 diagram that is wiring – Transfer Switch Connection):

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

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


The ShorePower track & the MeanWell Power Converter should both have their light that is green ON if all of the wires, such as the wires towards the transfer switch, happen properly linked. .

  • To try the machine turn the ENABLE Switch ON and disconnect from shore energy. The green light on the MeanWell is certainly going down and in around 20 moments our product will auto-start your generator.
  • Let generator run for around one minute then re-connect to shore energy and our device will immediately shut-off your generator in more or less 10-12 moments. The light that is green the MeanWell should come straight straight back on.

ESSENTIAL NOTE: switching the ENABLE SWITCH On or OFF will not impact the green light on the ShorePower track or MeanWell. In the event that ShorePower track is correctly connect along with coast energy those two light can be on. The ALLOW CHANGE merely enables or disables monitoring.

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