Cruise Control:

Our LSA complete harness packages can be setup for use with manual transmissions and 4L60E/4L80E/6L80E/6L90E automatic transmissions. This complete package is for use with the E38 engine computer and designed for use with any aftermarket high-flow fuel pump utilizing our included high-flow injectors.

If you all ready have, or want to piece together the other items on your own, please see our LS-58x standalone wiring harnesses or LS-58x harness packages (which includes the programmed E38 and ETC pedal). We can set those up for use with the LSA engine as well.

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

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.

Reprogram 6L80/90 Trans Module?: Select yes if you will be sending in the transmission module found inside the 6L80/90 transmission. For instructions on how to remove this from the transmission, please click here.

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 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 TCM for reprogramming, just select 'Yes' above and send your TCM to us and include a copy of your invoice that is emailed to you after you checkout.
