The product itself has 5 stars but I had a small problem. I literally took 4 steps and then turned the key just enough to turn on the light and saw that it worked. After closing everything I tried to start my 4runner but it wouldn't start! So I was like WTF?! I put the original 10 fuse back into the INJ socket in the engine compartment fuse box. My 4runner started, but then the check engine light, TRAC OFF, and the Multi-Terrain Disabled message came on. So WTF even more! Eventually it went away after a few starts. I went to the reviews and read what everyone else was doing. So I tried what some people suggested. I took the original 10 size fuse, put it in the fuse socket that came with it, put it back in the INJ slot and now everything works. I drive a 2019 TRD OFF ROAD.
