As far as I know it is legal, I know a couple of people that use them, we don't.

If it is JUST a pressure switch, I suppose you could adjust it to make or break at a certain pressure, but I don't see where you can adjust it for a delay.

And actually, there are a lot of trailer brake systems that use a pressure switch in the brake line, and they are adjustable for pressure. So a brake line pressure switch can be classified as an automotive part.

I suppose, if you were so inclined, and had plenty of time, you could put a brake pressure gauge in the car, figure out the minimum pressure it takes to hold the car on the line, and set the switch to turn the two step on and off at that exact pressure. I suppose you could disguise a line lock solenoid as a brake pressure switch, if you looked hard enough to find the pieces.

I know a few people who use the factory brake light switch. I know others who use a button in the brake pedal itself.

I know a few who use a switch on the pedal or the brake light switch and a switch on the steering wheel. But the switch on the steering wheel doesn't work like most people think it does. If you think you can just release the switch on the steering wheel and it will launch the car, you are mistaken. If you have an A, B, or C car and you try that, what will actually happen is you'll blow the tires off the rims, it'll just spin. Further, it'll never react at the same time or the same way, because your leg won't move the same way. And you can't use the brakes to set the car in the lights, get on the two step, and let off the brakes, either, the car will move. The REAL reason a lot of people put a switch on the steering wheel is so they don't accidentally re engage the two step later by stepping on the brake.

By the way, I've had a look at the inside of a couple of transmissions from the winners car's, one way or the other. There's NOTHING in them, except drums, bands, and planetaries. No brakes, no delay devices, no tricks, no nothing but plain old transmission parts.
