Generic LS ECM/PCM Mounting Bracket Kit for GM LS1B 0411 ECM — CNC-cut steel pair, fits 1999–2006 LQ9/LM7 engines

Two precision CNC-cut brackets to securely mount GM LS1B/0411 engine computers to any flat surface during an LS swap.

Swapping an LS engine often requires relocating the engine control module (ECM/PCM) into an unfamiliar bay or custom firewall location. This Generic LS ECM mounting bracket kit provides a simple, robust solution: two laser/CNC-cut steel plates that adapt the common GM LS1B/0411 ECM body to flat mounting surfaces, reducing fitment headaches and saving installation time.

How does this bracket simplify mounting an LS ECM?

The bracket converts the factory ECM housing into a flat-panel-ready component, so you can bolt it where space and access make the most sense. Instead of fabricating supports or battling clearance, you get repeatable mounting locations that align with the ECM body.

• Ships as a pair: two identical CNC-cut brackets for both sides or spares.
• Designed to fit the GM LS1B / 0411 ECM body common on 1999–2006 LS engines.
• Mates to any flat surface — firewall, inner fender, or custom plate.
• Speeds up wiring and routing by placing the ECM in an accessible spot.

Will this bracket fit my LS engine computer?

These brackets are shaped for GM LS1B/0411 ECMs that share the same housing size found on many 1999–2006 LS-series engines. They accommodate the two-connector 24-pin style commonly finished in red/blue or green/blue.

• Compatible with LS1B / 0411 ECM housings used in many LQ9, LM7 and other GM LS applications.
• Matches the exterior body dimensions despite internal variations between ECM types.
• Not a direct electrical adapter — intended for mechanical mounting only.

What materials and hardware are used, and what do I need to install it?

The kit consists of two 1.5 mm cold-rolled steel plates finished with an anodic oxidation surface treatment for improved corrosion resistance and durability. Four small screws are required to fasten each bracket to the ECM body; these fasteners are not included, so plan to supply appropriate screws and mounting bolts for your chosen location.

• Material: 1.5 mm cold-rolled steel with anodic oxidation finish for toughness and rust resistance.
• Fastening: requires four small screws per bracket to secure to the ECM housing (hardware not included).
• Mounting: designed for bolting to any flat surface using customer-supplied hardware.

How does this bracket affect fitment and performance of my swap?

While the bracket doesn't change ECM function, it eliminates common clearance and orientation problems that complicate swaps. By providing a predictable mounting flange, it reduces trial-and-error trimming and potential interference with other components.

• Reduces custom fabrication time during engine swaps and relocation projects.
• Helps maintain proper connector access for wiring harness routing and diagnostics.
• Durable finish protects the bracket in engine-bay conditions.

Who is this for: Fabricators, mechanics, and DIY enthusiasts performing GM LS-series engine swaps or upgrades who need a reliable, straightforward way to mount LS1B/0411 ECMs to flat surfaces. Ideal for C10 restorations, custom chassis builds, and anyone converting LQ9, LM7, 5.3, or 6.0 engines who wants a clean, repeatable mounting solution without extensive metalwork.
