I have a gauge cluster installed and recently the temp gauge stopped giving me readings. Unfortunately, i bought the car with the gauges already installed, so I do not have any directions or any idea of what wires to look for under the dash. Anybody know what color wires i should look for or where i should start? Car electronics are a new thing for me. Thanks.

do you have a picture?
we might be able to tell what kind gagues they are and we can go from there.

you should have a sending unit somewhere in the engine bay pulling coolant temps for you.

 

see 3rd picture in my Sticky thread.

you see anything like that in your engine bay?

 

What gauge to you have?
And is it reading water temp, oil temp, etc.

 

we need pics.
get us those and I'm sure we can help you out

 

There's the pics. It's autometer.

 

And for some reason the pics didnt get posted.....

 

I got it for you XxChrisxX

Thanks Jon

 

Nice digital gauges there, Jedi

 

Might want to check the ground for the temp sender unit.
Depending on which on you have, it could be in the same place as Jedi has in his post, or its on the large radiator hose.

 

thank you sir.
if the gauges aren't reading anything, it could be as simple as a bad ground.

pop the hood and look for a sending unit device. it might look a little different then my RB one but it'll have wires coming out of it.

 

haha!!
jon: great minds...

 

Well, it doesn't look like the set up you have. I wasn't able to find the sending unit. I would take a pic under the hood but my camera just died on me. On a side note, i just got my blue footwell lights in. That will be my next project after i figure this thing out. If you have any other ideas, let me know. Im going to check out their website again and see if i can get any ideas. Thanks again for the help

 

Its probably on the large radiator hose.
Refer to the pic below, its the hose running horizontally across.

 

Still no dice. I will take another whack at it tomorrow when I have a bit of sunlight. Gunna see if i can't fix my camera too. Thanks for stickin with me on this.

 

Man, look at that rust.

 

LOL... one year attempting to drive in the winter and a few years without a garage will do that

 

Man I don't miss that.

 

Well, the mazda certified mechanic at the dealership couldn't find the wire for the temp gauge under the hood either. Could it some how be wired into the built in gauge?

 

that wire has to go from the gauge to SOMEWHERE in order to get a reading.
can you pop the gauge out and follow the wire?

 

I was trying to avoid that but i guess its what i have to do
