• LS knock adapter loom - 101-0305

If you are after a fuse box and relay also, purchase this bundle here: 109-9010B

Advanced features of the XtremeX ECU: 

• Fully programmable E-throttle control complete with capability of gear shift throttle blip and antilag.
• Cruise control.
• Two independent CAN modules.
• 30 general purpose tables (up from 20)
• All Motorsport features including full gear shift control, cruise control, traction control, antilag and launch control.
• Advanced closed loop lambda strategy and dual bank lambda control.

The terminated harness has the following features:

Designed to match the PC Link base maps IO setup so that most engines can be made to run with minimal interferance.
Provides spare IO via a “Spares” connector — extra capacity for sensors, switches, or custom additions.
Equipped with sealed JPT terminals in the chassis connector (TE Connectivity JPT family), with mating connector specs provided.
The harness includes multiple dedicated connectors for key components, such as:

     •Pedal connector (for DBW pedal): 5V, sensor ground, two analog voltage inputs
     •CAN2 connector: for CAN devices like lambda modules, displays, keypads, etc.
     •MAP connector: compatible with Link MAP sensors; adapter available for factory LS MAP sensors
     •Knock sensor connector: supports up to two knock sensors, with adapters available for Gen 3 or Gen 4 factory sensors
     •Alternator connector: for “F Body” alternators; provides exciter/lamp wire to terminal B
     •Transmission (“Trans”) connector: for reverse switch, DI, or other functions needing cabin signal
     •IAC connector: for 4-wire stepper IAC; if no IAC is used, those channels may be used for other functions (boost valve, NOS, etc.)
    •TPS connector: for cable-throttle sensors; if using DBW, may be repurposed
    •DBW (electronic throttle) connector: for DBW throttle bodies, providing analog inputs, 5V, sensor ground; may be repurposed in cable-throttle engines
