    Hello all!

    I'm installing a startx remote start system on my 2021 Tundra (H-Key).. Long story short, for the remote start you're supposed to cut the TPMS wire and route it to the remote start controller however it causes issues (Pops up with a TPMS warning).. This is solved by using 2 relays connected in a way that the TPMS is rerouted 'back to stock' when the key is turned to the on position.. That's beside the point though.. In the video I'm referencing he says he uses pin 85,86 of the relay.. one of which is ground and the other connected to a 12V source that's only active when the key is the on position and this is where I'm stumped. I see he's using a fuse tap, but I can't see exactly where he's got it connected.. Any help is appreciated!

    Here's the video: https://youtu.be/iQZgEd7OfBw

    Okay.. so after watching that video a couple of times and jumping in my truck to do some tests... I think I know what he's doing.. I suspect he's using that fuse tap to tap into the 'power outlet' fuse which I believe is what the cigarette lighter is connected to.. if this is correct, the cigarette lighter only gets power when the key is at least in ACC position and that's exactly what I'm looking for. Can anyone confirm this?
