Got my LEDs and the Resistors installed. Headlights, Hi/Lo, Hi Beam indicator and fog lights all work as they should

Can you provide details on the resistors you purchased and the installation of them? Thanks.

I also have the HW Star and I used these canbus decoders. Everything works perfect.

Yeah, definitely confirm. Thanks!

I don't want to install resisters, so if they're truly plug n play, I'll likely jump on em as well. I like the classic/traditional look of them.

Tried to install today, manual **** on the motor just spins and spins. No way to open it slightly to get to screw. Guess I need new motors. Ugh

The trick for me was to pull the headlight switch and then immediately push it back in, trying to get the headlight pods to stay put halfway open. Easy peasy access to all the screws.

These are the LED adaptors I used and work great
now if I can get the new motors or work properly I’ll be happy. I must have installed something wrong
