I've got my air/fuel ratio gauge hooked up. There is a power and a ground for the back lighting, I've got that wired up fine.

Then there is another connecter which has
Green wire- to the O2 sensor - no problems there.

Black - Ground - No problems there. Ran it through the fire wall to the frame. It was recommended.

But this has a seperate power, too. Red - For the LEDs that light up the actual reading. I realized this morning that since I had that pulling power from the same place where I have 8 LEDs, 2 neons, 2 strobes (sounding a little rice-ish? I get a laugh out of them. It's like a party in my hatch.) running off of also. I've got two 10s in the back on a 500W amp, and when they hit, it was making my gauge go down a notch. I didn't like it, so I decided to wire the Red wire for the reading into a different empty fuse spot. I believe it was marked Bat. which I figure stands for battery? Everything else is wired into one of 2 empty slots marked Ign.

Everything was working fine, the subs weren't bothering it, but after I drove it, the reading on the gauge stayed on. I didn't have time to work on it, almost late for work, so I popped open the fuse panel and just pulled that red wire, not wanting to potentially run my battery down any.

So my question is, where can I find some easily accesible 12v power I can splice into so the gauge will just be on when the car is running. I'm thinkin I might just run this wire through the firewall also, straight to the battery, and put a switch in there. Maybe that other empty fuse spot marked Ign. will do the trick, but what I'm looking for is it to not be affected by my subs hitting. I'll do some trial and error tomorrow, but for now, any opinions are appreciated.

 

Those single pin slots on the fuse panel are fine to use. Batt is a battery 12V constant and the IGN is 12V when ignition is on. Be sure to fuse the wire within 6inches.These terminals are unfused

 

not to hijack the thread, but i have a quick question, i am wanting to hook up some gauges (3) could i just splice them into the instrument panel fuse wire and put a bigger fuse in it?

 

Thanks, I appreciate it. I have a few inlines fuses running between some of that stuff. One between the neon's power, one came with the gauge.
