Does anyone have a source for the older 3-prong 12 volt plug for Engel/Norcold or older ARB fridges? I would like to make a new cable and finding this end is tricky without buying a $50 dollar premade harness.
You should be able to find a replacement still. I've emailed ARB about them in the past. You might want to post an ad for one here and over on ExpeditionPotal. I am guessing someone has a spare laying around.
I assume you are talking about: Amazon product
But the ARB fridge socket style?
