    Hey everyone!

    First post here and happy to join the community. I am looking to put a kill switch in my Tundra, and I'm having a hard time locating it online. I am hoping there is a wire I can tap into inside the cab, and I am really hoping I don't need to go into the relay box under the hood and tap in from there.

    Thanks :)

    Anyone? Wondering if this type of question isn't allowed on this forum as there have been many views to this page...

    Yeah. Take what Bubba says and make it happen. Post up pics for a tutorial as this is something nobody here has done.

    Check the build link in my signature.
    Pull down the manual that @BubbaW linked and search through the System Circuits. It will depend on what engine you have (there are different control diagrams based on each engine model - 2UZFE v8 or 5VZFE v6) and these older manuals actually include some system description information and trouble-shooting as well.

    My best guess is that you will find there is a wire from the ECU (mounted in the passenger dash) that runts to the EFI relay coil and another that runs to the fuel pump relay coil. The load side of those relays are tied together, so killing either one of those would effectively disable the fuel pump from running.

    Thank you all so much for your input and information, I really appreciate it! I am going to try my best on Saturday to find that wire and hopefully I can figure it out and share with you all a step-by-step process. I will start with what RainMain_PNW said and look in the passenger dash, as well as study the diagrams that Bubba posted. I am very new to electrical diagrams and I am unsure how to read them and how they relate to where there are located in my truck, but I am going to give it my best. I will definitely update you all on my progress!
