2005- Current LS2/LS3 Drive by Cable Manual Electronic Fuel Injection | Wiring Harness Automotive Wire Harnesses Manual and Instructions www.psiconversion.com #EFI #conversion #swap #LS2 #LS3 This harness is designed to be a complete wiring harness for the fuel injection system on General Motors 2005 and newer LS2/LS3 Gen IV fuel injected engines with Drive By Cable Throttle Body and 4L60E or 4L80E transmission. If using a 58x Engine (LS3, etc) then a Lingenfelter Crank Signal Converter box (available through PSI) is required so the 411 PCM (Red/Blue Connectors) can be utilized. The factory E38 or E67 controller does not have the ability to operate a cable throttle body. If using a 24x LS2 no converter box is required, however a 411 PCM (Red/Blue Connectors) is required. This harness is constructed with GM Delphi Connectors and Terminals with GXL/TXL (600 volt polyethylene cross-linked) wire which is professionally assembled and 100% quality inspected prior to shipping. This harness includes all wiring that is needed by the PCM to run and control the fuel injection system and transmission.
