Product Description

GM LS V8 Drive By Wire Engine Harness

 

This engine harness is for 2007-2011 Jeep wrangler JK when installing a GM LS GEN3 series engine 2004-2006 with Drive By Wire aka DBW Electronic Throttle Pedal. This is the bare bones that you need to install a LS GEN3 and have everything working as designed. We know it may seem like a lot of money up front but the time it will save you is well worth it. 

 

With the overwhelming amount of GM LS series V8 engines at great prices it makes this swap a home run.  

 

We know it can seem daunting to try and wrap your head around so many options, We try and make it a no brainer to get your Jeep up and running. Our harness comes complete with new relay-fuse pack and OBD2 connector under the dash and with only a few wires to splice into the existing Jeep its extremely easy to be up and running.

 

Completely redesigned.

The OEM engine harness provides us almost limitless room for design improvement. OEM wiring includes many features that enthusiasts will not utilize and thus they add unnecessary clutter and weight, as well as reduce the ability to esthetically accentuate the engine bay. Our harnesses are designed to be better than OEM quality with newer improved quality wires, connectors, and loom designed to last. They are more flexible and simpler by design than the OEM harness, and they are mapped out in the engine bay to offer the most appealing and maintainable installation we have found possible.

Our engine harness offers many revisions over the OEM harness. Our harnesses integrate the Jeep side and GM side harnesses into a single harness. The engine harness routes directly to the ECU with a factory style plug at the factory firewall connector. The bulk of the harness routes behind the engine and under the fuel rails which is most visually appealing and allows for factory engine covers to be used. We also now include a EZtach module that eliminates the need for a reluctor ring and make the swap that much easier.

The final result is a harness that features improved esthetics and versatility, easier install and maintenance, and premium quality and durability.

In 2004, truck engines went to a single 3/8" supply line, with NO RETURN LINE (returnless) except 5.3L L59 Flex Fuel vehicles.  For 2004, Flex fuel engines KEPT the return line. You will want a returnless system or locate a returnless fuel rail.

 

Reluctor Types

It is important to know which reluctor type you have, 24x or 58x. You can tell by looking at the reluctor wheel sensor: a black sensor is a 24x wheel, a gray sensor is for a 58x engine. The GEN3 will need to be a 24x reluctor with a black crank sensor. 

The following engines came with a 24-tooth reluctor wheel:

  • 1997–2004 Corvette, LS1 or LS6 (all were drive-by-wire)
  • 2005 LS2 Corvette
  • 1998–2002 Camaro/Firebird
  • 2004 LS1 GTO
  • 2005–2006 LS2 GTO, 2004–2006 SSR (LS2 and 5.3 liter)
  • 1999–2006 4.8-, 5.3-, and 6.0-liter Vortec truck engines
