Default STI Brake Variable Proportioning Valve (264824S000)

Does anyone know the intended / recommended location to install this part?

I suppose it obviously replaces the stock proportioning valve but I can't seem to figure out how it would fit in there. I expect some modification of the hard brake lines will be required, but was wondering if there was a suggested location in the engine bay to mount this?

Thanks for the reply! So it would intercept the two brake lines coming from the front, and output the same to the rear brakes? The brake pressure valve on the front strut and the ABS system can be left in place and untouched?

This is for a streetable track / auto X build. Brakes have been upgraded from stock 4/2 to 6/4 and also the weight distribution of the car has changed to around 61% front-bias (from 59% factory) due to weight reduction, so wanted to be able to adjust the brake bias.
