I did set that up. i think somewhere somthings not set right since i keep getting errors. Well i found a 4000 ppm sensor that i can connect onto the trans to get the correct reading. Now the question is what pins on the 93 ecm. It lists 3 wires and says they go to the speed sensor but the sensor is only 2 wires. Also the color code for the ecm connected to the speed sensor is different so i cant even follow that. Any idea how it would go?
