Chris asked for pictures of completed installs, so...
Here's some pics of my (ugly) install. Keep in mind that everything done on this car is solely for function (rallying).
I bought a trio of gauges, which don't match, but were the best gauges I could find functionally for each measurement.
1) AEM 30-4100 wideband.
-Uses the Bosch LSU 4.2 sensor
-Has a 0-5V output for datalogging
-Displays in digital and analog (LED ring) for reading at-a-glance. Innovate LC-1 only does digital.
2) Autometer Cobalt series electronic boost gauge.
-Uses GM-style MAP sensor, so I don't have to run manifold pressure into cabin.
-Quick response, stepper motor design.
-Measures vacuum as well as boost (some don't)
3) AEM 30-5131B EGT Pyrometer
-Uses standard K-type thermocouple
-Stepper motor drive, analog display for reading at-a-glance
-Auxillary output 0-5V for datalogging.
I made a plate to help me read my gauges better. There's a bit of extra material on there to mount a terminal block.
Here's what it looks like installed:
In this shot, the terminal block kinda looks like its powering the gauges, but it's really powering my rally computer. I cut a hole in the dash similar to what would have been there if the car had aux gauges from the factory, and ran power from the C200 connector's power window feed. Since my car doesn't have power windows, I now have a dedicated circuit with it's own fuse to power the instrumentation I've added.
Trying to get a couple perspective shots showing gauge pod rotation.
As you can see, I'm still working on it.
