Hiya!
Thanks for moving this thread into the Bit Science section!
For the modification, you need a soldering iron, a screwdriver to open the RC, and a cable with a DB9 male connector.
For my RC mod, we took the cable with the connector from an old DB9 extension cable.
Well, to display how the connector is soldered to the microswitches of the RC, I took apart my RC again, as well as the port-connector and took a picture: I colored the used pins of the connector to match them with color of the cables:

The colors of other DB9 cables may vary, so make sure to solder the right cables to the RC-microswitches!
I donīt have a Booster car (yet), but If the boost button of the RC uses a microswitch as well, you can solder it to the appropriate pin of the connector and use the fire button of the joystick.
