I got this light for my R53 Cooper S and the plug in for the harness did not fit the harness in the car. I needed to modify the circuit board and change the wiring harness in my car so that it would fit.
I ordered the NM power module and a K&N CAI for my '16 F54 S Clubman. Both were very easy to install with the attached instructions. Shipping and service were excellent and I will continue to buy any items I need from these guys.
