Cable Throttle Body 
The GM LS Engines 24x layover harness is designed for use with a cable throttle body and 4-wire stepper IACV. 
However, the Infinity ECU does support up to 2 Drive-By-Wire throttle bodies. Additional wiring can be added into the 
Infinity connectors to support Drive-By-Wire throttle bodies if desired. Refer to the included pinout for proper pin numbers. 
 
Drive-By-Wire throttle bodies incorporate idle control into the main throttle body, eliminating the need for a separate Idle 
Air Control Valve. If converting to Drive-By-Wire, move the IACV connector branch to a safe location and secure with an 
automotive grade tie wrap. 
 
 
Wideband 02 Sensors 
AFR1 (UEGO Sensor Bank 1) and AFR2 (UEGO Sensor Bank 2) plugs are for connecting UEGO wideband Bosch 
LSU4.2 sensors (AEM 30-2001) models only. The UEGO extension harness (AEM 30-3600) mates with the layover 
harness to the sensor (1 required for each sensor used). Use of any other type of wideband sensor can damage the 
sensor and/or the Infinity ECU. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
AEMnet 
AEMNet is an open architecture based on CAN 2.0 which provides the ability for multiple enabled devices, such as 
dashboards, data loggers, etc. to easily communicate with one another through two twisted cables (CAN+/CAN-).

Installation Notes 
 
Wiring Conventions and EMI 
The GM LS Engines 24x layover harness comes pre-wired with all connectors, fuses, and relays needed to operate an 
engine. However, the PDC does require extension/termination of the flying leads to their appropriate devices, and 
additional sensors and other devices can be wired into the harness as needed for the specific application. The following 
guidelines should be adhered to while completing the required wiring. 
 
A proper wiring job includes proper termination of the wire at the sensor. The wire terminal end must be moisture tight 
where it plugs into the sensor and it must have strong, electrically sound terminals. The preferred method of securing a 
wire to a terminal is to use a crimp terminal with NO solder. It is important to use the proper crimping tool for sound 
terminal construction. Plastic terminal plugs must have moisture tight seals. Inspect each plug to make sure the seals are 
in place. Di-electric grease can be added in the terminal slots to further aid in corrosion resistance. 
 
If a splice into a wire must be made and no solder-less terminals are available, then you must properly solder the splice. 
 
Noise can be a serious problem and can cause intermittent misfiring of the engine. Every precaution should be taken to 
prevent interference to the ECU’s operation. Resistive plug leads are REQUIRED. The GM LS Engines 24X Layover 
Harness comes with shielded cables for the cam and crank position sensors. These wires have shield grounds that are 
grounded at the Infinity ECU plug. They are NOT grounded at the sensor end of the cable. Attempting to ground both 
ends of the cable will cause a condition called ground looping and will remove any noise protection the cable has. 
 
To eliminate or reduce the chance of EMI, wires that carry high current must run in twisted pairs. An example of this would 
be the power leads from a multiple spark ignition system. These ignition systems can carry up to 100 amps for a couple 
milliseconds at the time of discharge, which induces a strong magnetic field in close proximity of the wires. 
 
The routing of the wire loom is critical to EFI system performance and safety. The following safety considerations should 
be made when installing the wire loom: 
 Heat protection: the loom should be placed away from or insulated from sources of heat. The obvious item(s) that 
should be avoided are the exhaust manifolds, EGR delivery tubes, and turbochargers. If it is absolutely necessary 
to route a wire in close proximity to any of these items, then a suitable insulator must be used. 
 Noise suppression: do not route wires near the HT leads. For coil-on-plug ignition systems this is not as critical. 
 Moving component protection: route wires away from moving components such as fans, the blower belt, or the 
throttle linkage. Also, make sure the wires are not under any strain when the engine is at full deflection on the 
motor mounts. 
 Never have the wires in exposed bundles throughout the engine compartment. 
 
 
Determining ECU Location 
 It is recommended that the ECU be placed in an environment that does not expose it to temperatures above 85° 
Celsius (160F). 
 In cases where the Infinity is to be used in place of the stock ECU, the location that the stock ECU occupied is 
suitable. 
 On applications where the ECU is to be located in a different position than stock, the interior of the vehicle is best. 
 The Infinity should be located in a place that reduces the length of extension wires from the PDC while 
maintaining an environmentally sound location. 
 The ECU location must permit the PDC to be mounted in a serviceable location. 
 
 
Power Distribution Center 
The PDC contains all of the Relays and Fuses for the entire harness, and should be mounted in a location which permits 
serviceability. Ideally the PDC should be located in the passenger compartment, or if necessary within the engine 
compartment as far away from heat sources as can be achieved. 
 
The PDC contains the flying lead bundle which must be wired to the battery, fuel pump and radiator fan(s), and switched 
ignition. Routing of this flying lead bundle should also be taken into account when determining the mounting location of 
the PDC. 
 
 
  
						

							 Rev A, 2013/02/05  
Required Wiring 
The GM LS Engines 24x Layover Harness comes with a flying lead bundle wired into the PDC. Each of the flying leads 
needs to be wired to an appropriate device, or sealed and tied wrapped if not used. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Power and Ground 
 The Infinity must have an electrically secure ground connection, which means that the battery negative must be 
properly grounded to the battery AND the cylinder head grounds muse be properly grounded to the engine. The 
ground wires must have perfect electrical conductivity, which means that there must not be any paint or rust under 
the wire terminals.  
 The Battery Negative (10AWG BLK) and Battery Positive (10AWG RED) wires must be extended long enough to 
reach the battery without having excess length. A 10AWG or larger gauge wires must be used to make the 
extensions.  
 The 3 Battery Positive (14AWG RED) wires supply power to 3 relays: 
1. FPump 
2. RadFan1 
3. RadFan2  
Each 14AWG wire can be extended with a 14AWG or larger gauge wire and connected directly to the battery 
positive. Alternatively, the 3 wires can be spliced together with a large enough gauge wire to support the 
amperage load of all three devices combined. The amperage load of your Radiator Fans and Fuel Pump is 
unique, and the wire gauge selected for your splice must be calculated correctly. Large voltage drops, burned 
wire insulation, and fire can occur from using too small of a gauge wire. Reference an American Wire Gauge table 
for more details on amperage ratings. 
 To prevent rust build up, we recommend applying a protective layer of dielectric grease, such as Standard Ignition 
SL-4, to the bare metal surface.  
 
 
Fuel Pump 
Run this wire to the fuel pump positive terminal. This wire provides fused/switched power to the fuel pump. A separate 
ground wire needs to connect the fuel pump negative terminal to chassis/battery ground. 
 
 
Radiator Fan 1 Positive 
Run this wire to the Radiator Fan 1 positive terminal. This wire provides fused/switched power to the radiator fan. A 
separate ground wire needs to connect the radiator fan negative terminal to chassis/battery ground. 
 
 
Radiator Fan 2 Positive 
Run this wire to the Radiator Fan 2 positive terminal. This wire provides fused/switched power to the radiator fan. A 
separate ground wire needs to connect the radiator fan negative terminal to chassis/battery ground.

Switched Ignition 12V 
The Switched Ignition flying lead (PNK-WHT) must be connected to the output on the ignition switch that supplies 12V 
when the switch is in the Start and Run position. The ignition switch output should be isolated, meaning that it is dedicated 
to the PNK-WHT wire, and should NOT supply switched ignition power to any other device. 
 
 
Perm 12V 
The Perm 12V/Fused 5A PNK flying lead can be used to power the ignition switch if the switch does not already have a 
12V source wired to it. 
 
 
Tacho Output 
The Tacho Output (20AWG ORN-WHT) transmits a 0-12V pulse signal. The Tacho Output can be configured in the 
Infinity Tuner Wizard to transmit the desired pulses per engine revolution in order to match the installed tachometer.
