Any more ideas? Or is there something I missed?

Wouldn't it 'work' if they were turned 'off' instead. Or is this a typo.

When I turn the switch for the yaw off it has the slip light appear.

I made sure the other one is setup correct by trying to turn the car on with the break switch off. If I have it off then the car wont start, only the ignition will turn on.

So as you can see I have setup both switches correct, but for some reason it will still not work.

My car is AWD, could there be another switch I have to change for that?

^^^ LOL! Every one of us has experienced (or fixed!) a "DOH!" moment. So simple it deserves a smack upside the head.

Thanks. Good luck on this.

What I would do next is unplug the connector at the top of the brake and see if that changes anything. It is very possible another circuit is being used.

From memory on the 2013 there were to connectors up there - a 4 pin and a 2 pin. It was the 4 pin that needed to be disconnected to allow reving while braking.

By unplugging the sensor I can't get my car in to gear. I would have to cut the sensor completely to find out if this works... Another day I suppose.

Start the car, put it in neutral, then unplug the connector. The car will shift from neutral to drive without the brake.

Was there another connector on the brake pedal? There is only one way the car "knows" if you are pressing the brake - through the switches on the brake pedal. I would keep unplugging connectors on the brake pedal until it works, and then work backwards to figure out exactly what signal(s) need to be modified.
