You can but it won't help your problem if the ECM is locking the convertor now at too low a speed now.
All a switch wired that way does is ADD a manual option , does not bypass the existing ECM control

Instead of shadetreeing the problem, I would be investigating why ?
I would start by checking the tan / blk wire from the trans to the ECM ;if that randomly shorts to ground somewhere it will engage the lockup the same way your new switch would.

K so i was looking at the transmission and theres that wire harness with 2 wires comin out can i just cat those and run those wires to a switch

There should be 3 wires at the TCC plug
What colors are the wires you have ?

can i just have pin b and pin d always grounded and then pin a connected to a 12v source. can i put a toggle switch on pin and just flip the switch on when i want to engage the torque converter
