JDM Fan controller

i think i gotcha. So the +12V "signal" and the ground from the fan controller basically "switch on" the relay.....which connects the fan to the power source

i wired mine up so that it has a constant (+) supply, and the ground is being switched through the relay (with a fuse inline)

any adverse effects to having it wired this way?

Lol we're sayin the same thing like a synonym, man. +12v signal = +12v constant supply. I just like to use the word "signal" so that people understand this lead doesn't have any real power going through it (like the +12v "87/30" lead does).

no, i'm talkin about the "supply"....the heavy gauge shit that runs through the relay to the fan.

I have it so that when the relay switches, it supplies (-), not (+) to the fan. (fans always are connected to (+))

i'm assuming it doesn't really matter, since it's just completing the circuit...but i wanna be sure

It's all good. Doesn't make any "more" or "less" sense. Definitely works.
