This is fairly simple, heres the wiring, i wouldve used a pic of the bottom of the board but didnt have one.
The button wires also go to the bottom of the board, and that is where i connected the wires going to the pad. I used that picture for the diagram, since I didn't have one of the bottom of the board.
After you connect the wires to the board, connect them to to the pad. There is probably a connector that will fit on it perfectly, but the Radio Shack in the mall didn't carry any thing like that and just told me to go to a different one, so I just the wires in the holes and used electrical tape to hold them. Test it to make sure you did everything right.
Now, figure out where youre going to put it. I chose over the current buttons which means either shaving them down or adding a hard plate over it. Then peel the backing, and stick it on there. Now, try to bend the wiring as flat as possible to get the grips to shut without a large gap between them and the frame.
Thats it, takes about 5-10 minutes to do.
Does it help with performance? Hell no.
Does it help battery life? I'm pretty sure it does exactly the opposite, since the LED is always dimmly lit even when the gun is off.
Does it make it look cooler? Hell yeah.
Do I have any pics of it on my gun? No, but i should next week.
I am in no way responsible for you ****ing something up while doing this.
