Forget the days of cutting, splicing, hacking and soldering your stock Mini ECU harness while under your dash or bent over a cramped engine bay. With the AEM harness extension kit, wiring into your 02-06 Mini Cooper ECU harness has never been easier. The AEM harness is simply a plug & play extension between your ECU and your OEM engine harness, allowing you to easily wire in piggyback computers, fuel controllers, data loggers or any other type of ancillary device that needs to be tapped into the harness.

The AEM harnesses utilize OEM Mini plug connections so you are no longer confined to wiring under the dashboard or in the engine bay. The best part is that with an AEM extension harness, your stock harness remains virtually untouched, allowing devices to be cleanly and easily uninstalled in a matter of minutes. The AEM extension harness is a great supporting modification for the AEM FIC controller.
