The LOJ J30 LSx Swap Engine Harness is a completely new harness, not a rewire service. These harnesses are universal LSx Swap Harnesses than can be used in your J30 LS Conversion using a Gen 3 Small Block Chevy with a 24X crank reluctor wheel. 

Harnesses are professionally constructed from Brand New GM Delphi Connectors and TXL (Polyethylene Cross Linked) High Temperature Wire to GM Specifications. All harnesses are 100% Quality Inspected prior to shipping. Note that harnesses are for non-emissions equipped vehicles and do not include air pump or EGR provisions. All harnesses require ECU VATs removal, available through LOJ. Please contact LOJ for more information.

Harnesses are available for Gen 3 Drive by Cable (DBC) engines.

All Harnesses come standard with Braided Loom Installed

LOJ Also offers remanufactured Gen 3 ECUs, LS2 and LS3 MAF Sensors, and Bosch O2 Sensors.

*Note: You will still retain your OEM starter/alternator harness.

After Purchase, LOJ will contact you for details regarding your exact setup, so the harness can be spec'd to meet your needs. Details we will need to know include Injector Type, MAF Type, Exact Transmission Used.


I was reminded this morning, two years after I bought my Z32 swap kit what a great company this is. LOJ is always there with excellent advice, not just great products. Best customer service of any company I’ve ever dealt with, and the highest quality swap parts available. If you want an easy, bolt in swap, this is it. Click Here to See Review
