ECU bring Hunt
Oooops - that title should have been "ECU Wiring Hunt". While wading through the murky instructions to install a G-Power supercharger on my 2008 Z4M, I have found it necessary to add a relay to the ECU. The relay requires a 12V supply for the water pumps (I'm hoping that they are the heaviest gauge red wires), and the positive wire to the pumps (easy). But it also requires an ECU ground wire and a red-yellow wire from the ignition. I'm clueless about the location of the last two, and I'm a little reluctant to guess. Any insight would be very much appreciated. My ECU box appears below:
