  • Where does this plug into on my 13 lml duramax 3500?

    Here is the installation manual: https://www.thoroughbreddiesel.com/assets/1/pdf/1036620.pdf

  • Does this plug into the obd2 port or in a different area, looking to buy a cts3 monitor but that plugs into the obd2 port. If this product does plug into the obd2 port, i will not be able to use both at the same time.

    Product does not use the OBDII connector. Yes can use with a CTS-3 monitor.

  • I have a '13 Duramax lml (deleted) it doesn't go into high idle anymore, only about 5 minutes when I first start it. Does this kit make it go from idle to high idle to keep the engine at 140° or more during normal running conditions. Like if you go into the store and leave it running will it idle itself up if it cools down below a certain temp and then back to idle when it reaches that certain temp?

    No temperature controlled settings.

  • Hi I have a 2014 GMC Sierra SLT 2500hd with the 6.6 Duramax it’s been deleted and has a efi live in it !!! I was wanting to know if the high idle kit would work with it and is there a install video to show me how to install it if it will work or do I have to have a mechanic do it ????

    Yes it will work. It is a simple plug and play unit.
