I recently installed an ABS LSD trans in my non ABS P5. I know that I do not have the speedo gear in the new trans. I heard that I could install a GPS speedo sensor and get a reading. I have a sensor that reads 8000 pules which is the same output as the stock signal. My issue is I cannot get it to work. I have 2 wires a gray wire and a green wire. I looked a schematic and they both seem to go to the PCM Any idea on what wire to connect?
