MaxxECU Harnesses

Pro-Race Engineering is a UK MaxxECU dealer carrying the full wiring-harness range — including universal flying-lead looms, breakout adapter harnesses and plug’n’play kits where supported by the platform. MaxxECU is a Swedish-designed standalone ECU range known for excellent UK and European technical support, fast firmware development and motorsport-grade IO.

If you’re switching to MaxxECU from a factory ECU or an earlier standalone, we can advise on the right harness for your application and recommend any additional sensors or auxiliary IO you’ll need. Call 01621 473023 for harness-and-ECU-bundle pricing and tuning recommendations — UK in-stock items dispatch next working day on orders before 2pm.
