Tach dreamer update: I've finished the 33 LED analog display installed in the display trim similar to my earlier BS2 tach. Those of you from the LA basin may have seen the only operational prototype of the gen 1 tach. I've finished the firmware (with the help of Prallax.com forum members) on a breadboard for a digital readout. It's running in my Yaris today. I'm changing the 4x7 segment display from red to green. I had a setback learning to solder surface mount chips for the analog display.
I'll have to do a version 1.1 layout before it's kit ready. I love the headrest video camera mount I found here. When success is apparent watch for the video coming soon to a forum near you.

Wiring question
A question for this installation....
Could you also tap the tach and illumination wires that plug into the main speedo panel? There is a tach signal even for cars without a tach display. I know becuase I plugged a canadian panel into an american liftback and the tach worked fine. cheers |

Tach is important to me. Hearing aids, and excess road noise make it impossible to hear the little hum of the engine.

There isn't much diff between the Auto and 5 speed, (I imagine thats why the epa guesses we'll get nearly the same) I'm running about the same "R's" with my auto...a drop to 3rd puts me at 4300+/- @ 70.

Thanks!
I didn't think I would be turning so much at 70mph. If we had a 6 speed gas mileage would be close to the Prius. Ha, I guess that is why they would never put a 6sp in the Yaris! |

Followed this DIY, works fine. You can actually use any of the "top" row of the OBDII connector for ground.

There's ground right by your left foot. read the diy. why would you want to ground to a obd2 rather than a factory ground point

I did that out habit more or less as most all Toyotas have factory ground pont there. However, the OBD2 is closser so why not use it? |

The factory ground is better. Why tap into a wire thats a foot away from a ground point? The factory ground is exactly that a ground its not a obdii point it has a purpose use it.

A tach is a very low current draw item and the OBD2 ground is more than adequate. Don't loose site of the fact that if you are getting the tach signal frome the OBD2 to begin with, it will also be good for the ground. All modern tachs use LED/low current lighting. Otherwise, it would be like runninng a perfectly adequate 24ga wire for an item's positve and then, runing an 8ga wire for the ground for example. There would be simply no need for a 8ga ground.
