Painless GM Gen III LS Swap Wiring Harness makes your Jeep engine swap a simple task! This standard length harness allows four feet from the back of the intake manifold to where the fuseblock and ECM mount, perfect for those that plan to mount these components under the dash or in the glove box. This harness supports both flex and non flex fuel engines, (Flex fuel engines will require an inline fuel composition sensor in order to run E85). Included is a 10 circuit weatherproof fuse block & mounting bracket with GM color coded wires and labels for easy installation. Requires manual transmission or 4L60E, 4L65E, 4L80E, or 4L85E automatic transmission.
Please Note : This harness is standalone and is not intended to replace the OEM engine wiring.
