W163 PSE Vacuum pump

[Scott666]

I have a 1998 W163 ML320.
To retro fit a keyless entry system that also closes the windows I have to tap into the existing wiring at the PSE Pump.I was told that it was located under the main fuse board. That is not so. Does anyone know where it is?

I'll answer that question myself.
Mis-lead, the only vehicle that has a PSE pump is the SL range!!!!
