Any idea what are these for? There where not hooked up and all the electrical on my truck was (is) working.
And please don't tell me one of them it's a relay plug...
That's what I thought about that plug... being used for petrol... but the colors don't match.The later mains were made to be both petrol and diesel. On the Perentie we just converted to LHD the "extra" plugs were labeled "petrol only".
Also depends on how a truck was configured- ie a truck that left the factory as a soft top wouldn't have a relay in the rear wiper relay socket etc.
A few mins with a wiring diagram with the wire colors would figure out what the 5 pin relay plug is for.
