I'm really confused on what parts I need to get to upgrade my earlier 2013 build 981 without the brake light switch. Looking to upgrade to the GT3 version and there are two, one for earlier VIN's and one for later but neither has a description on whether they have the switch or not. Is it possible to just put the GT4 (really GT3) MC & booster on my car? Will it work without hooking up anything to the switch? Would I also need to get a new reservoir, they have different part numbers from the current one so not sure if it would fit?

For a 2016 GT4
Master Cylinder 991-355-130-84 911. With gt4. With gt3, from vin 183656
Power Brake Booster 991-355-125-83 Booster Cayman. 911. With gt4. With gt3, from vin 183656

For a 2014 GT3
Master Cylinder 991-355-130-80 911. With gt3, to vin 183655
Master Cylinder 991-355-130-84 911. With gt4. With gt3, from vin 183656

Brake Booster 991-355-125-81 Booster Assembly 911. With gt3, to vin 183655

Not sure of any of this but am curious why would you do it? I’ve seen for years on forums folks doing this but never asked why.
