Connectivity to the L-caches was handled by the BSB (Back-Side-Bus) for as long as cache has been implemented on-die. I'm unsure if this is the case in the most modern CPUs, but there is no integral reason to change this, so more than likely.

How does the system bus contribute to the overall system performance?

Your data busses sends information from component to component i.e. your FSB (front side bus)/system bus/internal bus communicates between your CPU and RAM, the faster it runs, the faster information is moved between your RAM and CPU giving your CPU quicker access to that data.
