Adapter harness used to split the vehicle speed sensor (VSS) signal
This simple one-piece splitter will work with GM’s smaller style VSS sensor found on many 96-up 4 speed transmissions. This allows the signal from the speed sensor to feed 2 different computers like a Holley Terminator, Dominator, or HP and a stock GM ECU so you can retain factory gauges and other functions.


  • Works with GM vehicle speed sensors (p/n 10456568 or similar)
  • Simple plug and play connection
  • Covered in braided style wire loom
  • 8″ length gives room to plug in and tie out of the way
  • Extra adapter to swap wiring on one side of the splitter to compensate for GM and Holley variations
