"Clutch bypass" would just be a jumper to close the contacts (or open them in some cases, depending on how it's wired in the first place)
All that is needed is to get the right signals to the controller, and wire it so the controller can flip the right relays at the right times.
In the world of Plug and Play this might not be possible.
but I have discovered that this board, and the members comprising this aforementioned board, are the robust Do it Your (owndangself) kind of folk.
trun any number of them loose with a BRZ, an off the shelf Universal remote starter kit, bits of wire, connectors, maybe a multimeter and a schematic, and it WILL happen.
(oh, and snacks, maybe a beverage or two to "enhance" the thinking processes)
it's just like herding,
you just gotta get the electrons from point "A" to point "whatever" through gates (relays/switches/transistors) through slogs (capacitors/chokes/resistors) down one way streets (diodes/triodes/pentodes)...like a miniature flea circus, these electrons perform for us as we (hopefully) wish them to.
I helped put a remote start on my friends VF750F back in the day, it was pretty cool, but we wired the interlock to the neutral lamp circuit. just in case. Neutral lamp on, remote start...lamp off...no go.
The honda dealer said it could not be done...
My friend worked as a subcontractor on defense missile projects.
He hated being told that "It couldn't be wired that way..."
...hide and watch...
