tail light wiring converter problem

Hi guys,
I'm stumped. Wiring a '27T track roadster w/302 Gimmy 6. Using 2 2-pin tail lights, trailer 5 to 4-wire converter from 3-position on-off-on switch. Hot to center pin with flasher. Input side half of connector has: ground, brake power in, left turn, right turn, running lights. Out half has left turn, right turn, running lights, ground. No matter how I wire it, I have no power coming out the turn signal wires. If I take the converter out, the turn signals work fine. The running lights (probably just a pass-through wire) is OK. The ground is OK. But no turn signals or brake lights. I am on my fourth new converter, by two different manufacturers. What am I forgetting?
Thanks,
HPace
