I'm going to be upfront with you, that I'm not the most well versed with things like buck converters or LED controllers. I was under the impression that all I needed was to wires in some resistors in a specific manner and I was good to go, but this is either something that I'm willing to learn, but will need help, but I understand if you recommend I find an automotive electronics installer instead.
As far as trying to do this, which I still intend to do, This is all of the instruction they've given me, with the LED's. Thanks so much!
