Ah, But it did have foil on it... (usa)
old post but here is some more information. i know a lot of people had to ask where to get their constant 12v source from when the car is turned on. the best place to get constant 12v source from only when the car is on is from the ignition wire in the ignition harness. if anyone wants wire colors, check below. also, i have not done this yet though i plan on it and was wondering if anyone knows a good pillar pod that has spots for two gauges. i am not a fan of the autometer ones as they are black and just cover the existing a-pillar plastic it looks likes. i want a complete replacement. thanks in advance

I installed mine today! : ) It does jump until the car warms up and then gets used to the ECU adjusting, then it kind of calms down.
Only complaint: No backlight! Oh well. Maybe I will take it apart sometime when I get really bored and attempt to add one! : ) Hee hee

I installed my A/F guage today. I spliced into the Pink wire w/ blue stripe at the first O2 sensor and my guage jumps back and forth when i'm at idle. I just read into the thread about splicing into the second O2 sensor for a steadier reading so I will be doing that tomorrow. Hopefully it will keep it from jumping around so much. Also have an DSM's AFC on order so we'll see if that calms it down a bit too.
alright i just got mine in and i want to clear this up before i go and put it in. I got 3 wires; red, black, and purple. tell me if i got this right: red goes to 12v input, black to negative ground, and purple to sender? i'm going to tap into the pink with blue stripe wire from the 1st O2 sensor. if someone could clarrify it that would be great. thanks in advance.
edit* i also hear all these suggestions for a good ignition source for the 12v input. i planned on tapping into my cigarette lighter with my water temp gauge but is there any closer wires in all those harnesses in the drivers foot well?

the explanation of the wire colors & what they are for is correct

you actually would want the 12v to be a 12v ignition source

alright, pm me w/ your email address & I'll send you the instructions for installing a turbo timer. This has the instructions of how to get to & which wire is the one you would want. Once you find that you would just basically tap both wires into the same line.
