Yes it would be but grounding that wire will not guarantee lockup at least not full lockup , Its one enables it with the pump , Unless the PWM has been in some way disabled you would have to also ground one wire from it to get full converter lockup , Otherwise you will only get a certain percentage of lockup as the PCM will allow at any given throttle

Off the top I would say you want a DPDT switch like:
side 1 - common to TCC solenoid on trans, NC to the
PCM TCC solenoid drive, NO to ground
side 2 - common to TCC PWM on trans, NC to the PCM
TCC PWM drive, NO to IGN +12V source
Then normally-closed (NC) will be normal operation and
the other (normally-open, NO) will be hard-locked with
full TCC duty (100%).
You might substitute a DPDT relay and drive the coil with
a cuter, pushbutton switch etc. and maybe add a LED
indicator just so you don't get hung up; if you are into
relay logic you could make it latching and unlatch with
the brake light etc. too.

I lock my converter on the dyno only.
Pin 42 tan/black red connector is correct.I have the insulation on that wire stripped back a bit so I can attach an alligator jaw style connector that goes into a small box that has a light and a meter[shows 0-100] and an on/off toggle.A second wire from the box goes to a good ground.
When the car shifts into 3rd gear the toggle is turned on,the light goes on and the meter shows 100.You can hear the converter lock up in third and then the pedal goes WOT and you get a nice dyno sheet.
You could make it nice and simple by bridging a wire to the lock up wire[pin 42-tan/black] run that wire inside your car where you want it and connect to one side of the on/off toggle.The other side of the switch gets wired to a ground.Turn the switch on and the converter will lock.
WARNING-Never leave the converter locked when comming to a stop it will hurt the transmission.
