For $327.00 we will clean, degrease and modify any Gen 4 LS to make it Stand Alone. Connect just 3 wires to make it run.
LS Standalone rework turn around time is two weeks.
Every LS Gen 4 Harness gets a new Delphi Automotive covered fuse/relay block. Included is a relay for the ECM and one for the Fuel Pump. Correctly rated Fuse protection for all circuits and a 5' long OBD Port are a part of every finished standalone harness we ship. All parts and materials used are real automotive spec materials not something from the local electronics store or home improvement center.
A module for controlling (2) Cooling Fans is available also. Fuses and Relays are rated at 30 Amps max each Fan. Uses the same Delphi Automotive base and Dust Cover as our fuseblock for a factory look and performance spec.
Gen 4 Engines are: LS3 LY2 LY5 LY6 LH6 LMG LC9 LH8 L76 L77 L96 LFA LZ1 L92 L94 and L99 engines. Most of those engines are controlled by the the GEN IV E38 ECM.
We are specialized in the correct modification of the Gen 4 LS E38 ECM and 6L80E or 6L90E powertrain harnesses. The T43 TCM will maintain it's memory and shift the trans correctly after every shut down and startup.
Whether your donor engine, ECM and harness came from a Silverado, Sierra, Yukon, Suburban or Escalade, you can be assured that your swap will run and shift as well as it did in the original vehicle.
Both Truck and Car based LS powertrains are supported. Some examples of car engines are Camaro, Pontiac G8, Corvette, and Caprice PPV.
Easy 3 wire hook up (Batt Pos, Ignition, Fuel Pump). Also provided are outputs for check engine light, and an OBDII diagnostic data connector. The easiest solution for gauges is to use CAN Bus plug and play gauges but there are alternatives to make factory or analog gauges work in your swap vehicle. Contact me for various gauge hook up options.
All connections are labeled with easy to read laminated plastic labels (that won't fall off or smear) and a printed guide for making the final connections to your vehicle is included.
Every Circuit/Connector is separated in the harness for an easy, tangle-free installation, that allows you to route the harness and finish as you choose for that full custom look. Every LS Harness is shipped without Tubing or Tape Covering as shown below. We no longer offer optional re-wrapping of reworked factory harness. Note: G8, GTO, PPV, Caprice, Camaro and Corvette Harnesses are left intact so the layout over the engine is the same as factory.
When you drop off or ship your harness a complete checklist is discussed with you when it arrives. This way there are no surprises. If any connectors are damaged or missing you will know up front if there will be any additional costs beyond the basic service. Note that if connectors are missing it usually adds about $9 -$15 additional cost for each missing connector. Additional charges for cut wires and damage subject to quote.
Harness can be set up for any transmission you choose. It's possible to use a 6L80E, 6L90E, 4L80E, 4L60E, 4L65E, 4L70E, 4, 5 or 6 speed manual, T56, TR 6060, Powerglide, TH350 or TH400.
All wire joints are soldered and shrink wrapped with marine adhesive shrink tubing. No crimp style butt connectors are used anywhere.

Every Reworked LS Factory Harness is shipped without tubing or tape as shown.
Because many want the harness routed differently, we no longer offer the option to recover a reworked LS Harness with Loom and Tape. We can however provide a kit with the GM Spec tubing and tape materials that the installer can use to finish the harness to a factory look after it's routed on the engine.
