They fit, you just can’t plug them into the headlights. You will still have the signal function, they just won’t come on with your headlights as the LED headlights have a different wiring harness.
I work at a high school and have access to the mechanics shop, including cost on oil. I change mine every 6000km give or take with idemitsu 0w20 and a wix filter. I’m only 2 oil changes in on my 2025 lariat.
Nope. The whole thing took my an hour maybe, with it being wired in. I just got a @WOLFBOX 930. Probably better ones out there but it works fine for me.
