You don't have power to the transmission. Wire up 12V IGN to the pink wire. Ground the yellow wire to activate the transbrake.

That harness isn't going to work to make it full manual. Our D1 transbrake works great when setup in combination with our manual control box. Without the manual control box, it operates as stock, and must use a controller/PCM.

If you are using an LS style PCM you can use it to control the trans and HPTuners or EFI Live to tune it. If you need a standalone controller, we sell the US Shift. It's $550.

Yes,
The US Shift will control lockup as well.
