Getting the controller ready:
First you going to need to cut these parts of the controller and drill holes around the point I have shown in the picture. You can put the buttons where you fit best on the front. Hot glue them in.


Now for the back of the controller you can place the buttons almost anywhere around the back around the battery pack. Just have to make sure not to place your button that will touch and of the soldering point of the controller. Also in the picture you can see where to place the 555timer and keep your rumbles. Also you can put the potentiometer where you wish.

On the bumper controller part cut this of off the right side.


Here is a picture of the wiring of the 555timer.

Seeing that pin 3 goes to the buttons, we will be soldering wires to connect to one lead of every button on the front and the same with the buttons on the back. Don’t solder the front to the timer yet but Leave a Long wire to solder on to the timer.


Wiring for the B and Y added buttons. (
You might want to use RDC picture here)
We now need to take off the right trigger to solder wire to the B and Y points, since the litter buggers are to close on the front. You going to need to use the De-soldering braid to get it off .Then use the pictures blow to scrap the installation off of the points and solder on the wires. Use long wires for now.

Wiring for the A and X added buttons. (
You might want to use RDC picture here)
Use the pictures blow to scrap the installation off of the points and solder on the wires. Use long wires for now.

Wiring for the right and left thumb buttons.
Use the pictures below and push the wires through the holes shown. Use long wires for now. For the triggers solder a wire in the middle of the three pins and push the wire through the same hole as the thumbs in the picture.

If you want to power on and off your timer and a LED to see if it’s on or off continue reading or skip to the next step.
First you got to figure out which switch or button you want to use. Now you got to figure out which type of LED you want to use for the light. The power wire for the time is going to have to connect to the led and power button/switch, then to the power point on the controller. Ground of the other lead of the LED Don’t solder yet.
Click here...to many pictures on pageUse the yellow area for the switch/button and the LED on the second picture at the top.
Now solder the wires to the other leads of the buttons and turn the potentiometer half way up. Once the controller is together. Test out the buttons without the timer powered on. They all should working normal but the triggers. Turn on the power and all the added buttons should turbo even the triggers.
