Upgrading to 12v with RC power wheels

I replaced the 6v battery with a 12v but when I turn the car on and moved in any direction, it just pushed forward at full speed and stopped taking RC input.

I assume it's too much voltage for the RC module, can I some how separate it? I am not sure about how to do that. There are tons of wires, some are for the lights and speakers.

Here is the wiring under the seat.

It won't be trivial if you're not sure, but if you get some pictures of the PCB (without the case) top and bottom, I can probably tell you what you need to modify.

The modification would require buying a part (ideally a buck convertor - £/$ 1-2), setting it (requires a multi-meter), cutting some PCB tracks and soldering.

Basically, it would be separating the logic power and placing the convertor in-between to keep that at 6v, allowing the rest of the circuit to stay at 12v+.
It would also mean that a 16/18v upgrade later would mean no other changes.
