Generic LS ECM LSX CNC Cut Engine Computer Mounting Bracket for PCM Swap – 6.0/5.3 (LQ9 LM7 0411) C10

Engineered mounting solution for LS ECM swaps

When you’re swapping a GM LS engine, choosing a reliable location for the engine control module can influence the entire build. This LS ECM LSX CNC-cut mounting bracket is designed to secure the PCM to a flat surface, offering predictable placement that stays out of heat and interference from intake plumbing and moving linkages. The result isn’t just a snug fit; it’s a cleaner wiring route, easier service access, and a layout that adapts to different swap configurations. Use it as a solid backbone for the control system in projects ranging from retrofits to mid‑level builds, and you’ll notice how a well-positioned ECM can reduce guesswork during the early stages of wiring and installation.

Durable, precise construction

The kit uses 1.5 mm cold-rolled steel for rigidity, paired with an anodic oxidation finish to resist corrosion. The combination yields a sturdy mounting plate that won’t easily bend under vibration, while the smooth surface helps prevent galling at contact points. This attention to material quality means the brackets hold steady across heat cycles, road shocks, and long-term use, maintaining a consistent appearance as you work through calibration and testing.

Fitment you can count on

Designed to work with GM LS swap ECMs such as LS1B and 411 units, commonly found in 99–06 LS motors featuring red/blue or green/blue 24x two‑connector layouts. Even if internal connectors differ, many builders can place the brackets in compatible outside dimensions, simplifying mock-ups and final mounting. The kit is optimized for mounting on flat surfaces, helping you plan where the PCM will live in the engine bay or swapped chassis.

What you get

• 2 x CNC cut engine computer mounting brackets

Easy installation and practical benefits

• Four small screws are typically used to attach the bracket to the ECM body; hardware is not included.
• Provides a dedicated mounting surface that helps with cleaner wire routing and reliable clearance between the PCM and nearby components.

Why this bracket matters

Beyond the basics of attachment, the kit supports organized routing of cables, reduces vibration-induced stress on connectors, and helps you plan future upgrades with fewer fitment surprises. While actual results depend on your specific swap, many builders report smoother assembly and fewer mounting conflicts during early PCM installations.
