Build Your Custom Link ECU Harness Without Starting From Scratch
The Link ECU B Loom Medium (2LB) gives you a professional foundation for building a custom engine-management harness for compatible Link ECUs.
Instead of individually sourcing terminals, crimping every ECU pin, and assembling the connector yourself, the 2LB loom comes pre-terminated at the ECU connector with color-coded wiring ready to be routed and terminated for your specific engine and vehicle.
It's an excellent choice for engine swaps, custom builds, race cars, and standalone ECU installations where a vehicle-specific plug-and-play harness isn't available.
Why Choose the Medium B Loom?
The Medium B Loom provides additional wire length compared with a short loom, giving your installer more flexibility when positioning the ECU and routing wiring throughout the engine bay.
That extra length can make a major difference when you're building a clean harness around:
Custom ECU locations
Engine swaps
Modified engine bays
Race-car electronics
Custom sensor locations
Relocated fuse and relay panels
Cut the wires to the length your application requires, terminate them at the appropriate components, and build a harness specifically around your car.
Pre-Terminated Link ECU Connector
The difficult ECU connector work is already done.
The Link 2LB features a pre-terminated B connector with individual wires extending from the loom for integration into your custom harness.
Depending on your ECU configuration, these circuits can be used for functions such as:
Fuel injectors
Ignition coils
Crank and cam sensors
MAP and TPS signals
Coolant temperature
Intake air temperature
Fuel pressure
Oil pressure
Flex fuel
Boost control
Cooling fans
Fuel pump control
Auxiliary inputs
Auxiliary outputs
Switches
Engine protection functions
Made for Serious Standalone ECU Builds
The Link ECU B Loom Medium is ideal for:
K-Series swaps
LS swaps
Honda/Acura builds
Nissan/Infiniti builds
BMW engine swaps
GM performance builds
Turbocharged applications
Naturally aspirated race engines
Drag cars
Road-race cars
Custom street builds

Cleaner Wiring. Easier Installation. Professional Results.
A standalone ECU installation is only as reliable as the wiring behind it.
The Link ECU B Loom Medium (2LB) gives you a proven starting point for creating a clean custom harness while still giving your installer the freedom to route and terminate each circuit specifically for the vehicle.
Whether you're wiring a street car, turbo build, engine swap, or dedicated race car, the 2LB helps eliminate unnecessary connector work and gets you closer to having the engine wired, powered up, and ready for tuning.
Compatibility Note: Verify that the Link ECU B Loom Medium (2LB) is the correct B-connector loom for your specific Link ECU before ordering. This is a flying-lead loom intended for custom wiring and is not a complete vehicle-specific plug-and-play engine harness.
