Does the adjustable diff on a classic impreza RA need anything connecting to the factory fit handbrake in order to function correctly ??
I'm fitting a hydraulic handbrake but there is a wire that connects to the factory handbrake, presumably for the handbrake light on the dash, but i just wondered if it did anything else too
I know that when the handbrake is operated the diff switches to the "diff free" position regardless of where the control/indicator switch is...even if fully locked.
So thjere must be some connection between the handbrake and diff controller.
