Orange wire/Black stripe coming out of your PCM middle connector.
T into it.
Run it to a switch and ground the other side of the switch.
Manual jump your trans relay.

Realistically,it is for testing purposes,thats about it. Anyone using it for anything else without a controller,will forget it on and end up trashing there trans.When used properly with a controller,it helps give engine braking and keeps the tc locked when wanted, if the trans is built to take it,with billet parts,and good tc,and internals,it can be good,as it provides 100% power transfer when locked.
It is also used by guys who got enough money to mod the motor,but are too cheap to buy a good torque convertor and trans,and try to get by by locking the stock TC to accelerate quicker.They quickly fry the lockup out of the tc,and forget it on as well,trashing 3rd gear and a few other parts.
On a 2001,there is no reason to lock the tc manually,as it locks in 3rd from the factory at WOT,and stays locked while it shifts to OD.The 99 and older trucks would not lock WOT until almost wound out in OD,or until OD off was selected,then it would unlock to shift to 4th,and relock when OD was turned off.

I use mine on my 01 when towing to keep the temps down because factory locks up at higer speeds. but have not been towing since I found my cooler was plugged so it may not be that big of an issue with a good flowing cooler. but would say he should upgrade his parts before doing this as it can fry a stocker real quick from what i have seen. but you do know if you don't turn the switch off as it will shake the crap out of you.. but I have heard of a way someone wired it like a controller so as not to forget to turn it off
