Alright. Some pictures.
Engine bay as it is for now.

Old Miata batt on the charger.
In front of that, power steering lines simply joined together.
Around the same area, Oil temp cable loosely in engine bay.
Near fire wall, a clear hose going from the BAC valve to the intake pipe. (Might redo that sometime.)
Next to the air filter, the S5 OMP set aside but still hooked up to its wires so it don't throw a code. Using a S4 OMP instead.
Secondary throttle plates removed.
The new oil filter pedestal I won at DGRR'09.
Oil temp cable and where it leads to.
Gauges I bought from advanced auto parts years ago, with light switch.
