I just did a T56 swap from a T5 on my 91 Z28. I was wondering if the VSS from the 97 LT1 T56 will work in place of the VSS that was on the T5. My speedometer is not moving and I am not getting any power out of the ECM on the 24 pin connector. I'm not getting any power out of the 4000ppm VSS. I believe thats B11. I checked the VSS high and low and they seem to be ok. I also wired a dakota digital SGI-5 box and played around with the outputs and it still didn't work. Is the pin on the ECM suppose to get power to it, because it doesn't with the key on or the motor on, or the car moving.
