Default 2 step off brake pressure switch ?

Plan to hook up my 2 step off a brake pressure switch but have a wiring question
How do u wire it correctly so it doesn’t activate at the finish line when I would get on the brakes on decel
I don’t have a clean neutral valve body
Any advice on how to wire correctly would be greatly appreciate
Thanks Bob

Put as micro switch on your shifter so the two step will only activate in low gear

Sounds like it would be slow to react hooked up like that.

I've got my switch set at a pretty high pressure (Folk Race Cars "The Answer"). So unless something drastic happened and I locked up the brakes. I don't think it would engage anyways. But what I did just in case. Is I put a toggle switch on the dash. It has one of those red switch covers on it like something out of a military plane or vehicle (summit sells then as well as a lot of the chain auto parts stores). I have the cover up on the starting line and the switch is on. After I leave. I reach over and hit the red switch cover and when it comes down it turns the switch off. After a couple runs it becomes second nature. .And I don't have to look to make sure I'm turning off the right switch. I can do it now without even looking.

I thought the rule book said the wire had to be unbroken from hyd. switch to the twostep. I could be wrong.

Then put the on/off switch in the wire that supplies power to the hyd. switch.

Our switches are set pretty high and not very much chance
that we will hit the two step when braking unless we go totally
crazy on the brakes.

Just thinkng out loud, why would activating a two-step at the finish line be a problem? You have already let off the gas and most race converters stall at 4500 and above so if the 2-step activates at say 3500, wouldn't the engine just freewheel?
Besides on another note, if your shifter allows going to reverse by accident at the finish line, you need a better shifter. My hand is on the handle ready to neutral before the line, then I brake.

Im referring to the hydraulic pressure in the brake line taking longer to release the switch when you take your foot off the pedal. How would that action be equal too or faster than using say a transbrake switch on your shifter? The action from using a transbrake switch seems like it would be much quicker. Is there something im missing here? Thanks
