Installation instructions for the H11 Pro series for 2019 Toyota Highlander are incomplete. I recommend that the wiring to insure polarity is correct and the wiring connection from the led to the external fan cover is correct requires that the connectors have red alignment marks imprinted on all connectors. This would eliminate issues with polarity and improper pin adjustment for the four pin connectors. Also it’s too difficult aligning the dust cover since there needs more notches to grip the cover. You need another installation video showing both driver and passenger sides. Toyota has almost no room to install replacement H11 leds or halogen bulb.
