With add a circuit does that gauge always stay on or am I suppose to use a certain fuse slot? I got everything wired up thanks to the how to on here. But I only want it to come on when I turn the key. If I want to wire it what would be good wire to wire into? Also what if I put wideband sensor in my badmab header temporarly???

 

Lol found my answer. You actually use the wiper fuse lol. Thanks for all the answers!!!!!

 

Im putting on my wideband today and was just thinking about add a circuits because i already have something else using my wiperblade fuse

 

Sunroof is another one that is only powered with key on.

 

already using that one too
