E9X/E8X Stage 3 Fuel Pump Activation Harness

This harness helps you activate your second fuel pump with a manifold boost reference. Our harness gets boost reference directly from the manifold and is not affected by charge pipe throttle closure pressure spikes like other designs. Also, this harness is a complete trunk mount setup and does not require any wiring to be routed to the engine bay. Includes detailed easy to follow install instructions.
