As many caravan manufacturers are component assemblers with little to no knowledge of Australian Standards and believe them only to be guidelines: With Caravans ALWAYS Check with a multimeter or test light.

No, motor would not run in reverse - as you would have positive (12V) connected directly to the earth terminal which would create a short circuit. Test lamps easily purchased under $10
240 V (AC) standards do not apply to 12V (DC).

I am talking about a 12v pump motor with a brown and blue wire i believe if the 12v positive red wire supply was connected to the negative blue wire on the pump and the negative black wire returning to the supply was connected to the positive brown wire on the pump the motor would run harmlessly in reverse. A $10 test lamp will illuminate whatever way you connect it to a battery. My electric winch will run forward and backward and that is just a change of polarity. Not a short circuit. Is this correct ?

When using 12v (DC) test lamp or probe, you test for current by attaching assumed positive to probe/light clamp, then touch a known earth (eg. Chassis) to test if current flows - if no light, no current flow from assumed positive.
Many DC components are directly earthed by means of their attachment ie metal body screwed directly to an earth - caravan and car lights for example. Your winch is designed to work in forward and reverse - not all pumps can run in reverse due to flexible centrifugal blades that could jam against pump housing if reversed. I am unaware of pump type, van type, or toilet type for original query by Hino, therefore as an engineer I would always recommend to ascertain polarity before connection - particularly if the item being repaired required assembly prior to test, if even only to prevent having to disassemble again.
I again advise that many manufacturers are only component assemblers and do not follow Australian Standards or Codes of Practice - therefore never assume their wiring harnesses are compliant to any standards.
