Ok i want to do this SO bad. Im not new to electrical work when it comes to LED's etc.

I am however new to car mod's and GP ownership in general.
It seems pretty straight forward to do the door switches from the images shown. I am concerned with the heater buttons and dash( spedo, gas etc) now you guys were saying there is a coloured overlay preventing a simple Light change for the dash? same for the HVAC? How do you get around that.

Thanks
