I have this kit on my rsx, unfortunately, I didn't take the risk to install it myself and hired a pro, after looking into the manual, it says you need to find ECU or IGN fuse to use it, I found a diagram for 370z fuse box but IGN marked as 50A which will not work, as the limit is 40A, tried to get a better diagram with no luck (as my car isn't here at home)
