Electronic Guages
I have installed a ScanGuage. It was $180 incl shipping from http://www.scanguage.com. That site has photos of the guage from all angles, and the cord.
It has a round black Cat 5 cord. One end of the cord has a large plug that goes into the diagnostic port under the fusebox in the pull-out cubby in the lower left dash. The other end of the cord has an ethernet plug that goes into a port either on the side or the back of the guage. The guage mounts with velcro pads to the top of the cubby over the steering wheel. If mounted to the bottom, the steering hub will block some of it. See Chadfo's photos at https://www.scionlife.com/forums/vie...ight=scanguage, this one in particular:

I used the port that is hidden on the back of the guage, and let the cord come out under the guage and creep discretely down into the crack around the top and right side of the steering cover. It looks so good that removing and drilling the dash for complete concealment of the cable is not worth it to me.
I coiled up the excess cord, wrapped it with a plastic tie, then hung the coil from a harness with another tie, and inserted the big plug into the diagnostic port. Here are photos of my installation:

When I started the engine, the ScanGuage introduced itself to the ECU and then knew all its secrets. As described above, there are 3 modes and the info in each mode can be displayed 4 items at a time. I started off in Guage mode and chose to display temp, volts, ignition timing and engine loading. I might change the last two to rpm and mpg, or there are lots of others. I wish it could show oil pressure but apparently the oil pressure sensor is just a simple switch that does not put out analog readings for the ECU to convert to digital.
If the Check Engine light (officially called the MIL or Malfunction Indicator Light) should ever appear, you set the display to Scan mode, and it displays the trouble code (DTC or Diagnostic Trouble Code). To find out that the DTC means, you go to http://www.troublecodes.net/Toyota/. Then you have a better chance of fixing it yourself, or at least you can discuss the problem better with the dealer.
In Trip mode, it will calculate a lot of distance, time and mpg stuff, but you have to input tank size and then input some fillup data each time, so I am not into that yet.
