GM LT Engine Controller Mount
This modular mounting solution integrates the GM LT1 or LT4 E92 Controller and Fuse/Relay Center Mount into a single, clean, compact system. By strategically stacking the E92 controller and fuse/relay center, this mount significantly reduces underhood clutter, providing a secure and easily accessible setup. The anti-grounding protection prevents unwanted electrical grounding paths, safeguarding your ECM.
Perfect for high-performance applications or cramped engine bays, this mounting solution not only streamlines wiring but also delivers a professional finish.
GM LT Engine Controller E92 Mount with Stackable Fuel Pump and TCM
Bowler’s second offering is designed for optimal engine bay efficiency, combining the GM LT1 or LT4 E92 Mount, 10L90E TCM, and Gen V Fuel Pump Controller into one integrated solution. This compact design allows for seamless stacking of the Fuel Pump Controller and T93 TCM Transmission Controller, which not only conserves valuable space but also minimizes clutter. The anti-grounding solution is included to protect the ECM from unintended electrical grounding paths.
The top relay plate is fully rotatable by 180 degrees, allowing for flexible routing tailored to your unique wiring layout. This intelligent, bolt-on system consolidates three separate mounts—the E92, TCM, and Fuel Pump Controller—into one cohesive unit.
