Ranger Tail light swap

[78Fairmont]

Another question for you guys. I have a 94 ranger that i swapped in the 2000 style tail lights (2 bulb reverse light on the bottom).

I have read up on the 2 bulb to 3 bulb conversions, and understand electrical diagrams pretty well, but i cant get it to work.

Here is what i did:

I am trying to change my 3 bulb setup (tail/brake, turn, reverse) to a 2 bulb setup (tail/brake/turn, reverse). I have purchased 3 different taillight converters and nothing has worked.

The converters that i tried only had the running lights working, nothing else. I checked and triple checked everything, its all hooked up correctly, but i get no juice to the 'major' filament being either brake or turn. I even bought a trailer plug adapter for my truck, and tried to wire it off the trailer wiring, but i got the same thing, the brake/turn didn't work. Any help is appreciated.


------------------------------------

What i am having problems with is getting the brake light to shut off when i have the turn signal on. Right now, i just have the brake and turn hot wired to each bulb (no converter) and i am using the 3rd brake light as my brake light. The tail light converters were hooked up properly, and i cut the one green wire that runs side to side to split the brake function on each bulb.

I even hooked the converter up to just a battery to see what it was doing. When i applied 12+ volts to the converter 'tail' function, the the tail on the otehr side lit up. When i applied 12+ volts on the brake or left or right turn, none of the wires on the 'trailer' side of the converter had juice. I read the instructions in the tech article and it still didnt work. I need to figure out how the tail light converter works or else need to find another way to get this job done.

Any help is appreciated. Thanks fellas.

um, can't you just.... maybe it's not grounded well enough? run a wire from where you think is ground and put it to actual ground... see if that works.
