Trailer Wiring Harness Recommendation for a 1999 Isuzu NPR  


I am trying to convert my Asian Isuzu NPR truck chassis wiring to accommodate pulling a trailer with flat 4 prong connecter. It appears a model 11975 would work however, I have two different trailers. One has LED lights and one has incandescent lights. I notice the model 11975 does not like LEDs. What model converter would work for both applications? Or do I need a powered converter for my truck.


Expert Reply:

What you need for your Isuzu NPR truck is a powered converter # C59236. It is compatible with incandescent and LED trailer lights. I have included a link to the installation instructions for you. This harness does require a direct connection to the vehicle battery to power the trailer lights. I have included a link to an FAQ article that offers tips on routing the power wire.
