There is a kit that is offered by many different companies that incorporates a pressure switch that will engage lock up when the transmission shifts into 4th gear. It is not necessary to wire in any manual switch or a brake switch even. The reason is when the transmission downshifts the TCC solenoid will lose it's signal.
That is how it's done buddy! Just do a google search on 700r4 lockup conversion harness or something similar and you'll find exactly what you need. If you have any questions feel free to get back to me.

Installing that kit will take alot more time, pulling the pan and such, plus you'll lose the lockup feature for 2nd and 3rd. But it does have a manual lockup switch and cost $83.95. Wiring it through the break switch is simple, cheap and retains all the lockup features as the factory intended.
Not trying to argue here, but having built and installed 700r4's for over 20 years I might have a bit of a strong opinion. There are many ways to accomplish lock up in a 700... i prefer the hands off while driving, non manual switch approach myself.

You can beat the snot out of it and it will be fine.
Just like Heads-Up said... it will only lock up in 4th gear and will release when it is not in 4th gear. It cannot apply in any other gear. Now, the only downfall to it is there is no delay feature... meaning it will stroke the solenoid and engage the TCC as soon as it shifts to 4th.
Hope that helps.
