  • Plug and play solution - No soldering required!
  • Standard looms are covered in 3m fabric adhesive lined tape to give an OEM look
  • A long length of cable is provided on the Fly-By-Wire throttle pedal cable to give you the option to route it through the glovebox side and across inside the cab, or over the firewall and through the grommet behind the brake booster
  • Supplied with an OE style OBD port to be located under the drivers side kick panel as it would be in an E46, on a quick disconnect plug so the cable can be routed through the firewall grommet
