Hey, so im installing gauges in my 97 TT, and this is my first time. I found a handy write up (https://www.supraforums.com/threads/gauges-wb-made-easy-writeup-included.521301/) using a relay and terminal. I liked this because it allowed me to manage things better than tapping my radio, clock, and the cig lighter. Im just a tad confused on how to get direct power from the battery to power the relay. Do I have to tap my wiring harness? I saw these battery terminals where I can run an 8 gauge wire from it and connect it to my relay. And then, from the relay, I run to ground, 12v switch from add a fuse, and 12v switch power to the terminal. Or am I getting this whole thing wrong and am I not supposed to run direct power from the battery to the fuse.
