F90 High Pressure Fuel Pump upgrade.

[m5rosco]

Hi everyone.

I’m upgrading my HPFP’s to the OEM F90 versions.

I have the pumps and wiring harness adapters on order.

I’m struggling to find any info on wiring. There’s only two wires, which colour goes to which? Or doesn’t it matter?

Thanks in advance!

I think your car is in the LCI age group and may not need the adapters. I just had my 2015 M6 done and did not need the adapters for my install.

OK that's good! My car is a late 2016 car. The adapters were only £20/$25 from dealer, so not the most money I've ever wasted!

Yeah the connectors did not break the bank for sure but I bought them just in case. I figure someone might need them one day so I have them in a bin mixed with all sorts of other odd bmw parts.

Keep us posted on how it works out.
