6640 sl with factory cab and a/c.. fenders have no tail lights and I'm having to road this tractor between hay fields. WHERE... are the plugs to plugin the fender mounted taillights.... I have NO plugs at the b pillar or c pillars after moving the cab foam out of the way. I do.. have a taped up wiring harness that passes by but no plugs to add these lights to. Tractor does NOT have work lights at the top or license plate lights at the top either, but I can at least see the harness turn and go up the c pillar to where those light would have been on the roof. I am looking at the waist line area for the tail light plugs as per "11d03" drawing suggests that they should be there. via 8, 9, on the right 10, and 11 on the left.. at the c pillar, just below the glass. TIA Bill
