Harness Manual

Online Instruction Manual 

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:

  • 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
