Harness 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.
With the addition of the fusebox, this package Includes main chassis “flying leads” (un‐terminated wires) for essential power and control, including:
Large red “Batt+” wire (for ECU main power)
Red-Green “Fan” wire (ECU-controlled +12V to cooling fan), rated 20A continuous
Red-Blue “Fuel Pump” wire (ECU-controlled +12V), 20A continuous
Grey-Black “Ign Sw” wire (to ignition switch)
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 bodies, providing analog inputs, 5V, sensor ground; may be repurposed in cable-throttle engines
