I'm ready to build my FW now, but I have four questions about the rules. Does the removable link need to disconnect both positive and negative, or just one, if so, which one? Do I need a switch as well as a link? Do I need a separate switch/link for the lifter (it's not pneumatic)? Lastly, it's a 360⁰ degree lifter, so how do I satisfy the rule on tethering it with a chain? Thanks.
