MAP sensor location for E39?

Hi all,

Trying out a HHO kit I have an eletronic box to be wired to a "MAP sensor". But where can I locate the MAP sensor, and where can I find a wire diagram for the cable between MAP sensor and ECM/ECU (according to instructions). The instructions I have are general instructions, and not explicitly for BMW.

Yes, the instruction says "MAP/MAF" sensor so that's probably it.
