Mine is nothing more that a $.50 toggle switch from Radio Shack. One side is connected to the T/C lock up wire. The other, to a ground. When you flip the switch it grounds out and locks the T/C. It took me about 15 minutes to install. The hardest part was figuring out where I wanted the switch.
I use mine mainly for when I am pulling my 5er. Keeping the T/C locked, I can do engine braking. And the tranny doesn't go into coast when you touch the brake.
As for other benifits, you can lock the t/c over 25 mph and do some serious acceleration.
Anything under 25 mph and your engine starts to stall.
Any way's, I wouldn't think of towing with out it again.
