E9X/E8X/E60 BMW PNP MaxxEcu Harness

Are you looking to save time on wiring your LS swap? Are you not a fan of cutting up your factory wiring or not a fan of wiring in general? 

Our PNP MaxxEcu harness will connect to your E9X/E8X/E60 chassis (N54 & N52 originally) and allow you to connect to the MaxxEcu LS harness with almost no work required. Our PNP MaxxEcu harness provides power to the MaxxEcu harness and provides connections to the pedal, starter, cooling fan. ECU box fan, etc. 

The 03/07+ harnesses come with an Ignition/Brake signal amplifier board to prevent weak 15WUP and brake pedal signal issues.

If you are building a custom engine harness you will need to wire the MaxxEcu 12 & 16 pin connectors according to our pinout.
