Noise filter wire?

[7Mboost]

I cannot find out where to hook up my noise filter wire, does anyone have a picture or where the other end of the noise filter wire comes from? I have the side coming out of the engine harness but idk where it goes?

pics would be good bro.......comes through ign coils/into efi resistor/ending in ig2.....color for wire is wht with blk stripe to blk with orange stripe? i believe....should end to ground on engine block it says.

Is that even the correct term for what you're talking about? A picture would be fantastic, or a diagram of what you're talking about.

yeah, its a fancy name for a ground wire, lol

Ahh, thank you that goes to the manifold, the lower intake runner. I may be able to find you a picture one second.

 

[7Mboost]

Looks like this?

 

[92TealSupra]

Ahh that goes to a sensor that should be bolted on the body, I think it runs one of your gauges, if you can't find it I will go take a pic of what mien looks like.

See that blue connector there on the right side there? its on the body udner the strut tower. Your's may be a Grey connector even. or black.

Here better pic for you

Sweet thanks, what does this wire do anyways? I think it may be causing my ignition problems.

SO did you find where it connect to then? Was it where I placed mine?

To tell you the truth I am not sure. I wish I did, Maybe Ill find out really quick. if ti does then that's a good thing that you put it back together.

I'll check tomorrow, the car is at my dad's shop.

I looked at the wiring diagram and it looks like it should plug into an ignition noise supressor.

It's function is to filter out ignition RF noise from being picked-up by your stereo (in the form of a electric sounding whine out your speakers). Probably helps with ground loop noise as well (constant humming sound).

Ahh I was still trying to figure out what it does, but I make sure it's connected all the time. Good luck!

mine is under the fuse box.....some are on strut tower depending on year

Mine is missing, does this piece interupt the coil and ignitor? I see its all connected on the tsrm but would this prevent my car from starting or give me any problems? I wanna know before I go buy a new piece.

Well there only one way to find out start the car, you will not be hurting anything, and again it may be a resistor I thought, for a gauge, but it seems like you have it figured it out

Yes 92 teal got it. it's around that area.

Ok do you know if this piece being disconnected would cause my car to not let me get a breaking groung to 2 out of my 3 coils?

A noise filter is only there to keep RF noise out of your other electronics. It should be pluged in, and if its not you will hear a whine in your stereo. But its possible it could ground other things. I would have to look it up on the wiring schematic. I'll take a look at it later.

Just glancing at it, it looks like the ignitor has a black and orange wire that is shared with the noise filter, then grounded after the noise filter thru a white and black wire to the engine block. But I would say double check that before you do anything. I dont have the time to go thru the entire wiring diagram right now.
