There's lots of talk on the web on where to mount the bung, but I don't see much in depth on the electrical side of the install. As in, running wires for the gauge and wideband controller for key on power sources and grounds. And then the SCT Firewire for logging AFR/boost values into Livewire.
I currently have the controller inside the center console and the o2 sensor connector goes into the shifter boot, meeting the o2 sensor plug by the x-pipe. There are smart guys who have removed one of the front narrowband sensors and put the wideband sensor in place. Their setups have controllers that can send a narrowband output to the PCM, keeping the PCM happy and also allowing the driver to see wideband AFR. This is probably the cleanest install but it is over my head so it's out of the question for me. I took a shortcut and removed one of the rear o2 sensors and put the wideband sensor in its place. I will get around to getting the wideband bung welded.
The controller and gauge are wired into two separate fuse taps in the SJB for key on power. The controller shares a ground with the Firewire grounds, and the Analog 1 (orange) wire is connected to the Analog IN on the controller. This is an Innovate LC2 if that matters. Because the Firewire uses a chassis ground (seat bracket bolt), it's permanently attached to the car. When I am not datalogging I plan on burying the Firewire between the console and seat. The gauge is on it's own ground by the a-pillar footwell.
I hope all of this makes sense. I will update with pics if necessary to help explain things. I'm wondering what you guys have done to get this setup wired in without snaking wires everywhere through the cabin or drilling holes in the panels. I'm not the most creative type so drilling on either side of the center console is the best I could come up with. With the wideband controller as the "median", I can have one set of wires go the the driver's side a-pillar for gauge output, and another set of wires go to the passenger side to get power from the SJB. The orange (or red) Firewire pigtail will be permanently attached to the controller input.
