Vapor barier between room above garage and garage

I am finishing a room above an insulated, but unheated garage. The garage has sheetrock and insulation on all walls and ceiling. I assume a vapor barriere is installed on the walls of the garage. Above the garage, we can see that the fibreglass insulation R13, was installed with the vapor barriere side facing towards the garage.
I have been told a number of conflicting things to do by various contractors. They range from
1. leaving it like it is and simple installing the T&G plywood over the insulation 2. flipping the insultion so that the vapor barriere is facing the floor of the room above the gargage
3. slicing the vapor barrriere up so there is no vapor barriere between the spaces.

I am seeking the correct answer.

I am by no stretch of the imagination a professional. However, I have done insulating and the rule of thumb is the vapour barrier goes on the heated side (facing interior) of house.

Verify this info with your local building supply centre. They can advise you.
