s14 speed sensor not working??? HELP

[Arm4nii]

I have an S14 with an s13 transmission with the speed sensor already in where does the speed sensor pig tail plug into

[centralcoaster33]

S13 and S14 speed sensors are different. Both plug into the transmission wire harness. The S13 speed sensor has a wire coming out of it (pigtail) and the S14 speed sensor just has a plug, no wires. The sensors are not the same and you need to use the one that matches your ECU and car. So, if I read this right, you need to re-use your S14 speed sensor. One 10mm bolt holds them on. Just pop them out and swap them over, then plug it in.
