    Wondering if anyone has installed an alarm on their 2021 Tundra yet? On the compustar instructions it asks to connect a wire to the DCM 12V (+) wire on the 56 pin harness. Well there is no 56 Pin harness. I am assuming there was for 2018-2020 and perhaps 2021 changed ? I have two white ecu plugs and neither is 56 pin and according to the instructions and photos its in the same area. But 2021 looks slightly different.20210710_192424.jpg 20210710_183927.jpg

    Thanks everyone. I searched compustar on the Tundra Facebook page and seen a couple people say they install them and I asked one member. He told me it was on the back of connection box. Remove all connecting harnesses on the front and remove 2 10mm nuts and take it out. There are the correct harnesses on the back and sure enough there was the red wire on pin 33!

    I am using the T12 2 way remote as well. What module are you using? I am using CM-DC3.
