F/IC Wiring
I started looking at diagrams again tonight in anticipation of wiring the F/IC. Tonight's search was for a switched power source at the ECU for the F/IC power supply. Pin 28 on A21 did indeed prove to be a reliable source. I tested it and it is indeed a switched 12V source. So, that's good. I will find the signal grounds tomorrow. Since this configuration of a 2008 xD ECU, 2011 harness and 2ZR engine is unfamiliar to the turbokits guys and AEM, it will be an experiment for sure. I had a bit of a scare. I wanted to test my trans fan and relay by crossing the terminals on the trans thermostat sensor. It seemed that my EFI fuse socket (the one that powers the MAF - thanks Trevor for that one - and now also the power supply for the transmission temp thermostat) had lost power. I tested it numerous times and started to get a little depressed. I went back inside and started pouring over the wiring diagrams hoping to find another fuse somewhere that, if blown, would cut the power supply. It turns out that because I still had the right ECU connector (A21) disconnected, the circuit was incomplete. I plugged it back in and voila, power was restored. MAF has switched power and the relay for the fan works great too. Here is what had me freaked out before I discovered what was wrong.
