Caddy Tail Wiring

How do you wire up caddy tails so the turn signals work individually. I hooked mine up w/ the brake and turn from the truck to the yellow (green), and the parking lights to the brown. Everything works, except the seperate Left/Right. Thanks in advance.

The answer to the question is this...

On GM vehicles that use a dual filament bulb to accomplish both the brake and turn functions, there is a relay circut that disconnects the ground for the brake light on the appropriate side, allowing the signal to blink on one side. There are two relayed brake ground disconnet circuts, one for each side. Because Toyota uses a seperate circut for it's turn signals, I need to wire in a relay to disconnect the ground for the brake light on each side.
