  7. Use nail file and sharp blade to remove button limiters that prevent the button from moving in the module. Make sure that the button moves freely and without any restrictions.Volvo dome light modification
  8. Use nail file to modify module body so additional wires won’t be squeezed when the module assembled.
  9. Cover existing circuit with isolating tape (or neoprene in my case) to prevent short circuit.
  10. Mount the switch inside buttons module. Depending on what kind of switch you are using you have to think of your own way to place it in the module. I’ve added a piece of rubber tube for additional support for the switch. Just to make sure that it didn’t move deeper. Notice that the switch should at all time touch the button to prevent it from rattling.
  11. Assemble the module back with wires from the switch hanging out of it.
  12. Install the module back in your car and connect switch wires to device that you want to control with that button.
