Alright, I tried hooking it up in the car, and it's not quite working yet...

First, the voltage regulator was backwards. The screen flickered whenever it tried to turn on, so I fixed that.

Now, it's not showing any data from the car. Occasionally, the gallons/hour number will jump to something, but then it'll go back down to 0. So, I'm no sure if I tapped into the right line for the VSS signal. Here's a picture from the EWD for my Tercel, I boxed the VSS line that I used, and the injector signals. Do these look correct?


The Rostra.com manual also says that the VSS signal is pin 13 on that connector, so I think that's correct.

Is there anyway to see if they're the right lines using a voltmeter?

Oh, also, on my injectors, both connections on each injector showed-12V...I used the black-red wire because it looks like that would be the ground.
