Description
 
This section provides detailed descriptions of the options available to you when ordering a harness. This will follow the "Choose Your Options" area above.

Engine: Select the engine you will be using for your project.

Emissions Wiring: Our harnesses come standard with no emissions wiring (Post CAT O2s, Purge, EVAP, etc.). If your project requires emissions, you can select what you need here. All harnesses come with pre-cat O2 wiring, as these are required for proper operation.

MAP Style: Select which MAP you will be using.

On most LS-58x engines, the MAP is located on the front passenger side of the intake manifold, near the throttle body. There are 2 styles, Bosch and Delphi.

This is the Bosch MAP style:



This is the Delphi MAP style:


Sending in ECM/TCM for reprogramming?: Select 'Yes' if you are sending in your ECM/TCM for us to reprogram them. Once reprogrammed we will test your ECM/TCM with your harness on a test engine here to ensure proper functionality.

Use the Special Notes field above to let us know any engine modifications and gear ratio/tire size. Refer to the Special Notes description below for more info.

Air Conditioning: If you are planning to use air conditioning with your project, then you want to select "Yes" here.

MAF Style: This is where you select which MAF you will be using. If you need an LS2 or LS3 MAF sensor, you can add it to your cart below in the "Add MAF Sensor" section.


Determining Your MAF Style

This is the LS2 MAF:



This is the LS3/LS7 MAF:



This is the L92 MAF:




Transmission: Select the transmission you will be using with your project.

Special Notes: This is the area you will want to use to let us know about anything that would be important to us to know when making your harness. Such as which intake manifold you're using if not using the one that comes stock on your engine - like if you're using a car style intake manifold on your truck engine. Or if you're using a "Hi-Ram" style manifold. Anything that may affect connector placement, etc.

Let us know the Year/Make/Model your engine and transmission came from, as well as the Year/Make/Model of the vehicle you are swapping this into.

This is also the place to include any engine modifications (Cam, headers, etc.) as well as your gear ratio and tire size if you are sending in your ECM/TCM for reprogramming. If gear ratio/and or tire size is not known, everything will still operate satisfactorily, but shift points and speedometer may be slightly off. This info helps us program the ECM specific to your vehicle.

If you are sending in your ECM/TCM for reprogramming, just select 'Yes' above and send your item(s) to us and include a copy of your invoice that is emailed to you after you checkout.
