I know it's been discussed a lot, have c32 and want to have IC pump run all the time, I know when idling iat temps rise a lot.
have green wire and brown going to pump,
green usually ground brown would be hot, I was going to run wire from front fuse box that has power on all the time when key on to brown wire and just slicing into it keeping the ECU connected to pump???
So it should send power all the time even when ideling.
any one confirm that's right

 

Brown is ground on the wires that I have seen on this car. Brown is ground by European standards. I'll check the schematics though and get back.

 

Jump it in the fusebox.

Perhaps the C32 compressor is controled differently but for the slk32 and srt6, upon the first compressor activation after every initial start, the IC pump will remain on for the remaining ignition time hence, no need for this mod and yes, brown is ground

 

Sorry the 2 wires cmg from IC pump are red and brown. Red and brown
Brown would be power?

 

BROWN is almost always GROUND, RED is almost always POWER.

 

There is a YouTube out there showing how to wire it in the fuse box. Simple operation to keep pump running when ignition is on.

 

Surely on our cars brown is always ground? Or all hell could break loose when working on the wiring.
Red would be power in that picture, but that wire could be any color or combination of colors.
