The (mechanical) boost gauge I just got has 4 wires total coming out of it. The directions that come with it has a diagram like the fantastic one I made with MS paint. I'm following the AWE instructions, but I guess since this gauge has multiple colors there are more wires...

Purple and Orange wires go to the 12V ignition switch which I presume is the normal one that AWE uses for theirs (75X). Don't know why they didn't consolidate the two though...

The Yellow wire is where I'm a little confused. It says it is for the battery, but I don't know why it would need constant power since its a mechanical gauge and where to hook it up to. Is "30" (next to 75X) to the battery (see AWE photo posted)?

Also, the wires coming off the gauge weren't long enough, so I bought some 18 gauge bell wire. Should that work?
