Ride Tech e3 CPU mounting?

[biohazardbill]

Where are some areas you guys have mounted your ECU? In a perfect world I would mount it with the compressor/tank etc are however they are located in the spare tire area of my build (step side with tire carrier so no under bed tire needed). Being that far back the front sensor wires will not reach. I had thought about under the seat, but that is a huge hole to drill in the floor for all the wires and under the seat would hide the excess wire. So I figured I would ask you pros where you mount yours?

Thanks in advance.
