Sorry guys but I've been searching the internet and reviewing all the S866 manuals but I haven't found anything that tells me for sure what these two wires are for (photo). Something to do with the headlight? Thanks for help.
I found a fan-made unofficial S866 user manual (attached); I needed to be sure about voltage. Also, wires named "lamp" come out of the controller...I still need to know better about the difference between both types.
I've a headlight should that is red & black, but both harness connections are black. I'm not about to use & maybe
fry something. I've got a rechargeable (USB) light kit i'll use. At least it's bin tested.
