For those of you who have asked about my oil pressure gauge, here are a few pictures of the install.
First, the sensor end. The gauge is an Autometer 4353 full sweep electric gauge, and this picture is the sensor install. The sensor requires an M12x1.5 adapter to the 1/8NPT sensor. You also have to rotate it with an elbow because it will hit the side of the valve cover if you don't. If you disconnect the stock idiot light sender, you don't get a code but the light stops working. Watch the guage when you start the engine.
Second, getting the wire through the firewall. There's a rubber boot for the clutch fluid line and I just pushed a piece of 1/8 plastic hose through it (oil sampling hose) to act as a conduit for the wiring. The harness is long and has the gauge connector on one end and the sensor connector on the other. I cut the gauge wiring harness in the middle so I could put it through the small tube, and then reconnected it under the dashboard.
Third, the view from outside. The picture quality sucks but it gives a sense of what it looks like from outside. If I was to do it again, I'd put some sleeving on the wires so they weren't visible from outside.
Last, the driver's view (there's only one guage - the upper one is just a reflection caused by the camera flash on the inside of the windshield). Again, the picture isn't the greatest, but you can see what I see. Very visible, but out of the way. The guage is the same color as the dash instruments so it's ok visually. If I was to do it again, I'd pick the "ultra-lite" series of instruments - the lighting is better. It works fine as it is.
The guage is attached to the A-pillar cover (easy to remove, drill and reinstall - just keep the bolts as far forward as possible - you CAN clear the airbag very easily) and the wiring just runs around the edge of the dash by the door, and goes underneath the dash. The light wiring and the switched power and ground are available off the back of the combined instrument by tapping into the wires on the connector closest to the door.
Installing this is not a job for the uninitiated - it takes some courage and the tools and skills to lie upside down and solder wires together and shrink-wrap the result. That said, it's not complicated. The wiring to the instrument panel is the trickiest, and the Bently 5 series manual is handy for the wire colors to pick.
