TC lock questions

Today I tried to do the TC lock up mod. I got the correct wire under the hood, I verified this by putting the truck in gear and grounding the wire out. It killed the truck instantly. So, I then hook up the wires to the switch and nothing happend when the switch was thrown, except the lighted rocker lit up. I'm using a lighted rocker with 3 terminals on the back, 12+, Acc. and ground. I had the wires hooked up to Acc and ground and that didn't work. I then switched it to 12+ and ground and that didn't work either. Do I have to hook the wires up to the Acc. and 12+ terminals to get it to work?

Place the wires on 12+ from your power source, acc to the lockup, and then ground to ground and it should work. You ground the switch so it will light up.

I figured it out today, after having a day to think about it. Hooked the ground up to the Acc. terminal and the TC wire to the 12+ terminal, it works like a charm.

Ive read the page on how to do the mod, but how did you find it to do? Was it fairly easy to do? Do you notice a big difference after?
