WBO2 Extension Harness

  • Sale
  • Regular price $27.99
Shipping calculated at checkout.


Extension for either of the popular wideband sensors. (LSU4.2 or LSU4.9) We use these with our ECUs and the extensions are often useful if you're not making your own custom harness. Specifically made for the BMW M50 Plug and Play, they are universal in application. Standard length is 5 feet (1.5 meter), but can be customized as you desire. It will take extra lead-time in processing the order though, due to having to make a custom length extension.

Available by default with split-loom wire covering, or also available with fiberglass wire covering or Raychem DR-25 shrink tube wire covering.
