ECU Box SMG loom?

Hi guys,

Having an SMG is terrible during the hot summer days in stop and go traffic. I keep getting kicked into limp mode. I plan on doing the E46 M3 Resistor splice into the ECU to "manipulate" SMG Hydraulic Temps (well, as far as the sensor can sense).

I would like to know which wire in the ECU box is for the SMG. Can someone help?

It's the white wire (pin 21; see below pic) in the E46 M3. I checked my e85 SMG and there is no white cable in that loom. Can someone please advise?

I've never had the lid off my box, but it's only a matter of time.
It doesn't have a diagram on the underside saying which relay is for what?
Every other car I've owned did.
