I am trying to hookup my Apexi AVCR, it says to use SPEED SIGNAL. So I look and I can find 3 things that it could be

Pin 28 = Vehicle Speed output, used for Speedometer
Pin 48 = Engine Speed, used for Tach
Pin 58 = Vehicle Speed, used for Speedometer & VSS

I am guessing that I should be using the 28 one? I did a search and the only thing I can find is pics of a wire under the hood but it does not relate back to the ECU from what I can find :(

The vss wire is what you are looking for. Do you have a digital multimeter? If so then you can easily verify the wire that you are looking for.

I just looked again and I dont see it anywhere, I did searches and did not come up with anything. Not saying its not true because I know that you have been here for a long time so I am sure its there somewhere I just dont see it :(
