I am currently driving a 940 wagon, 1993 and have unsuccessfully attempted to wire for a trailer. I purchased the recommended converter (now no longer available) installed per instructions and have only working directionals, no tail lights or brake lights. To further complicate things the "bulb out indicator" is now on when I 1) apply the brakes or 2) turn on the head lights. When I step on the brake pedal the left tail light, where I wired the brake wire to, goes out.

The recommended wiring goes like this: the converter has five wires, three are wired to the car, and two are wired to the trailer connector. the three for the car are marked: left directional, right directional, and brakes, all of which I wired in with crimp-down connectors. the two for the trailer are marked: left turn and right turn, both of which I connected to the two turn wires on the four prong flat trailer connector, this still left the white neutral unwired and the brown taillamp unwired.

Can anyone help???????
