ok
want to wire up the RS this weekend properly, similar to how Adam (BlackRS) has done his, but have a question.
Using for example something simple like say a fan switch, wired like this.
Wire from fan to the battery, with a fuse box and switch in the middle.

what do i do about relays? do i need a relay and where does it go? do i just wack a relay in the middle somewhere or does it have to go in a certain place (before the fusebox etc)
