didn't expect I'd have to wire the barrelplugs?!?!
outside (sleeve) barrelplug = -V = black or white wire
inside barrelplug = +V = red wire
is that correct?
do you have to solder those connections + shrinkplastic ?
correct.
No need to solder, just a twist up to attach and reattach the plastic sleeve. thats how we've got them anyway
