Which DBW Pedal Works With Holley?

  • Holley's GM LS drive-by-wire harness (558-406) is built for late GM 6-pin throttle bodies and pedals: 2005–13 cars and 2007–13 trucks/SUVs.
  • Pedals it lists: GM 10379038 and 19417903 (C6 Corvette), plus Holley's own 145-160 pedal, which is plug-and-play.
  • It is not for older 8-pin pedals or 3-bolt throttle bodies (2006-and-earlier trucks, 2004-and-earlier cars).
  • Holley lists this harness for the Terminator X Max and Dominator ECUs, so plan on a Max if you want drive-by-wire.
