OK, I was thinking of adding LED brake lights to my 2012 Mazda5. I thought that it would be simple, with the differentiation being CAN bus or not (not, as best I can tell).
When I was getting to press the button to select the bulbs the website asked another question - SCK wiring or not. Huh? I’d never heard of this before, and apparently has something to do with where the ground connections are in relation to the signal lines.
I thought I could do everything online, but I guess now I have to break out the multitester or look at the existing bulbs. Well, it’s hot and I don’t want to go outside. I guess this project is now on hold...
