Does anyone know what the Taillight /Brake light number is ? I tried 3157 LED but it did not work. Thank You in advance

The 2017 manual suggests a "7443LL". A plain "7443" would probably work. If you're getting LED, I'd suggest getting "red" rather than "white".

Great thank you.

You always match the LED color to the lens color, i.e. red and red, amber and amber

Do you have issues with hyper-flashing turn signals with those LEDs?

Yes but I used the sylvania load resistors to fix this.

For the LED Load Resistors (Sylvania LED Equalizers) on the brake light/turn signals, which wires are we connecting?
