Help: Need Wiring Diagram for IC
Can anyone post or email me the wiring diagram or how to re-wire the intercooler so that the intercooler pump runs all the time or when the ignition is on? Thanks ahead for any response. FYI, I am referring to the E55 W211.

Don't have any wiring charts etc, but a post from Vrus which is what I did with mine. You can also tap off the alternator for a power supply for the pump so she only runs when car is started.
***Make sure you have a fuse somewhere in that cable going to power source in fusebox. Pretty darn close to the ECU in that fuse box. Scary.

Yes.. Definitely rig it to run continuously.. It makes a big difference especially when you are sitting still in a dyno room or at the staging lanes.
You can grab an Accesory 12V power from within the engine compartment, driver side, near firewall at the base of the windshield.. Lift the plastic box to expose the fuses and relays.. there is a thick RED wire with BLUE Stripe. Tap into that wire. It will only provide power when the accessory key is on or the ignition is on.
