They donโt have the diagrams right now, but that will be included with all the measurements needed to cut. Itโs somewhat straight forward. You remove the bumper, unplug a couple harnesses fog light, and camera if you have. Remove the crossmember. You cut that middle portion valance out and cut the fender flare trim pieces as there is a wing support bracket that goes underneath. And it bolts up using the existing mounts with the crossmember. Very similar to front bumper install like the 4Runners, tacos, that covert style bumper.
I didnโt install myself, I was fortunate enough to be able to do it at the shop. I have done an SSO slim hybrid bumper for the ladyโs 5th gen 4Runners with viper cut/support brackets to go with it, so that honestly the best comparison I can think of.
