Introduction 
This Infinity Layover Harness was designed for the GM LS Engine 24x (manual transmission). The harness includes all 
standard GM (or equivalent) connectors for direct plug-in fitment, and requires minimal wiring to complete the Power 
Distribution Center (PDC) connections. The Infinity ECU is sold separately, and includes base configuration files for the 
GM LS Engines 24x.

Power Distribution Center 
Included in the harness is a Bussmann Power Distribution Center (PDC), pre-populated with the required relays and fuses 
for correct operation of the harness. The PDC comes with a bundle of flying leads that need to be properly wired as part of 
the installation. Flying leads include switched ignition, battery power and ground, and switched power to Fuel Pump and 
Coolant Fans 1 & 2.

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...

Required Wiring 
The GM LS Engines 24x Layover Harness comes with a flying lead bundle wired into the PDC. Each of the flying leads

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...
