Transbrake, Two-Step, Linelock

According to the rulebook what you are trying to do is illegal.. you may never get checked and I'm sure there are people out there doing exactly what you want to do, but technically it's not right. You have to push 2 buttons on the starting line to engage all 3 systems (transbrake, line-loc, 2-step)

In general regulations section 20 page 32(page like 299 overall) it states this:

"In categories that prohibit delay devices:

Changeable vehicle

components, legal unto themselves (solenoids, throttle-linkage
components, hoses, springs, etc.), even though the removal and
replacement of that component may affect the reaction time of the
vehicle in relation to the driver action, is not considered a delay
device. Wiring may consist of a single (i.e., “one” or “1”) continuous
wire from a power source to a switch (or button), and a single
continuous wire from the switch to the transbrake OR line-loc
solenoid. One splice (no quick-disconnect) is permitted from the
two-step to the solenoid (i.e., between the switch and the solenoid).
All switches, buttons, wiring, solenoids, etc. must be for normal
automotive use; i.e., not intended to create a delay (adjustable or
non-adjustable) between release of the button and the resultant
action of the solenoid. All line-loc/transbrake wiring before and after
the switch must be separate from any other wiring and fully visible.
Computer wiring, sensors, relays, and the like may not be wired to
the solenoid wiring. Two-steps or other rev limiters that are
adjustable by thumbwheel, replaceable chips, and the like may not
be within the driver’s reach and will preferably be located outside
the driver compartment.

Any system that does not fit the above description is prohibited and
must be corrected before the vehicle will be passed through preevent
technical inspection. Further, discovery of a delay device,
adjustable or non-adjustable, at any time following pre-event

technical inspection will be grounds for immediate disqualification"

The red font above states that only thing that can interupt the transbrake wiring is a splice to the 2-step only. This means that if you would also like to hold the line-loc on the starting line to prevent the car from "settling" you must have a second button to push.

Trust me I think it's stupid. I also use the line-loc on the starting line because I stage so shallow the car had a tendancy to "settle" backward and cause an instant red light. I now have 2 buttons on the steering wheel, one for the transbrake/2-step and a second for the line-loc. Push and release both at the same time, works the same just a little more difficult to wire.

None of this applies of corse if you are running in a class that allows a delay box. I figure in the stock, SS section this was a SS so everything I posted would apply.
