I bought a narrowband af gauge from a friend to just see how it looks in my car. The thing is that I'm not sure how to wire it up to see if it lights up. I do a little wiring **** sometimes, but never did a gauge before.. So my question is how do I plug it into something to see if it lights up? Do I just pop a wire into a certain fuse area or something? I don't care about it reading, I just want to power it to see if it works. If the fuse idea works, will it also go off when the car is turned off? I've never done gauges again.. lol. Thanks!

 

connected it to your battery easy as pie

 

I believe display works on 0-5 volts. With out a diagram saying which wires go where your just guessing. Google the mfg and see if they have a owners manual on line......

 

So like just take the wire and wrap it around the positive terminal? haha Is it safe to leave it on there full time or will that blow it / just stay on the whole time?

 

if its an autometer narrowband a/fr gauge then there should be three wires.. red goes to any power supply that cuts off when the key gets cut off black is ground and the purple wire will go to the purple wire in the wiring harness goin to the ecm under the hood.

 

if you have a sunroof you can just use that powersource..and i think the purple wire goes to the signal wire on the o2 sensor

 

So to power it do I just slip the red wire into the fuse slot of the sunroof? Then the black grounds on an un-painted metal surface and the purple splices to the purple wire going into the ECU? Where's that located? And what kind of wire should I buy at the parts store? My existing wires are pretty short.. Do most gauges follow this similar installation? I am switching to a triple pod soon so I'll have 3 gauges going.. Thanks guys!!

 

yea just pull the sunroof fuse and wrap the wire on the fuse and plug it back it in ...any thin gauge wire will work..you do not have to hook it up to the ecm..you should just be able to run it through the firewall and go straight to the o2 sensor...its the signal wire

 

first thing is what kinda gauge is it you have?? name brand is what im askin. but yea you have it right with the install.. look in the how-to section and there is a how to wit some good pics of where the harness is in the engine bay. its a good write up on how to do this install.

 

yea the megan racing one i had i just went straight to the o2 signal wire

 

i didnt mean wire it to the ecm.. im talkin bout usin the signal wire thats in the main wiring harness that goes to the ecm..

 

yea i never figured it out thats why i went to the o2 it worked

 

ahh ok.. well its actually the same wire just a different place to tie into it at..

 

word

 

Auto Meter. Thats what this one is. And all the next ones will be as well..

So o, figured out everything so far.. But the O2 sensor? Not quite sure what that is and where I'd locate it? How do I make the other gauges read then? Like let's say.. Tranny temp? Or something like that. Umm.. What else.. Volt meter.. etc..

Thanks!
