ABS Speed Sensor for R154. This ABS speed sensor is for a R154 transmission in an MK3 Supra. Does your ABS light stay on after swapping a JDM engine set into your car? That's because the JZA70's didn't have ABS. Automatic transmissions use a different part also, so you can't use the auto sensor when doing a 5 speed swap. :( Don't just disable it, make it work with this new Toyota sensor! This sensor could probably also be adapted to other vehicles using an R154 with ABS.
