Maximum Wiring Flexibility for Your Custom Link ECU Installation
Building a custom engine harness where the ECU needs to be mounted farther away from the engine?
The Link ECU A Loom Long (5LA) gives you the extra wiring length needed to build a clean, professional standalone ECU installation without extending a shorter harness or adding unnecessary splices.
With a 5-meter loom, pre-terminated ECU connector, and color-coded flying leads, the 5LA is ideal for race cars, engine swaps, rear-mounted ECU installations, and custom builds where maximum routing flexibility is required.
5 Meters of Wiring – Route It the Way You Want
The biggest advantage of the 5LA Long A Loom is simple:
More wire gives you more options.
The extended 5-meter length allows you to position the ECU where it makes the most sense for your vehicle and then route each circuit cleanly through the chassis and engine bay.
It's especially useful when the ECU is mounted:
Inside the passenger compartment
Behind the dashboard
On the passenger side of the vehicle
Away from heat and vibration
In a dedicated electronics enclosure
Farther from the engine on custom race-car applications
Instead of extending individual wires later, start with enough length to build the harness correctly from the beginning.
Pre-Terminated Link ECU Connector
Building an ECU harness from scratch requires the correct connector, terminals, crimping tools, and pinout.
The Link 5LA simplifies the process.
The ECU-side connector is already terminated, while the other end consists of flying leads ready to be routed and terminated for your specific engine.
That saves time while still giving you complete control over the final harness layout.
Color-Coded Flying Leads
The loom uses individual color-coded wires to make circuit identification and harness construction easier when following the appropriate Link ECU wiring documentation.
Cut each wire to the required length and terminate it for your:
Injectors
Ignition coils
Crank sensor
Cam sensors
MAP sensor
TPS
Coolant temperature sensor
Intake air temperature sensor
Boost-control solenoid
VVT/VTC solenoids
Fuel pump control
Cooling fans
Relays
Switches
Auxiliary inputs and outputs
Engine protection sensors
Available functions depend on the specific Link ECU and configuration.
Ideal for Engine Swaps & Motorsport Wiring
The Link ECU A Loom Long (5LA) is an excellent choice for custom applications including:
K20 and K24 swaps
Honda and Acura builds
LS and GM engine swaps
Nissan and Infiniti builds
BMW performance builds
Turbocharged engines
Naturally aspirated race engines
Drag cars
Road-race cars
Time-attack builds
Custom race vehicles
Standalone ECU conversions
Why Choose the Long A Loom?
Choose the 5LA Long Loom when you know your installation requires additional wiring length.
Starting with a longer loom can help eliminate unnecessary extensions, splices, and junctions throughout the harness.
That means a cleaner finished product and fewer potential electrical failure points.

Which Link A Loom Do You Need?
Link offers different loom lengths so you can choose the right harness for your installation.
A Loom Short (0LA) – Best for compact installations where the ECU is located close to the engine harness.
A Loom Medium (2LA) – A good choice for most custom installations requiring additional routing flexibility.
A Loom Long (5LA) – The 5-meter option for installations requiring maximum wiring length and flexibility.
Build the Harness Around the Car
A custom standalone ECU installation shouldn't force you to mount the ECU somewhere inconvenient just because your wiring isn't long enough.
The Link ECU A Loom Long (5LA) gives you the length and flexibility to position the ECU properly and build the harness around your specific vehicle.
5 meters. Pre-terminated. Color coded. Ready for your custom build.
Important Compatibility Note
Link ECUs use different connector configurations. Verify that the 5LA A Loom Long is compatible with your specific Link ECU before ordering. Always use the correct Link ECU pinout and wiring documentation when constructing your engine harness.
