How To: Gauge Dim With Cluster Dimmer

[Professor MSP]

Guys I have the same gauge with MAP sensor.
I have no instructions and I saw that you connect the 12V source for the MAP to the fuse box. Also you guys connected the bulb power to the dimmer switch. Does this make sense?

Thanks

Yes, this appears to be correct. I have attached a pdf file with the installation instructions for the Autometer electronic boost guage.

Good luck!

The add a circuit did not work on the empty spot and i put it in the door lock fuse next to the one that you indicated. It worked but after 20 seconds the alarm went off and the car got crazy. I guess the alarm monitors that fuse.

So I broke the thing and I am going back to using the empty slot. Stupid add a circuit.

I will try to wire the light with the dimmer tomorrow.

I figured it out, i had to use the green lead at my dimmer switch as a groud for all 3 gauges, then i used the blue lead for the dimmable illumination to the gauges. I love it!!

I'm trying to hookup my gauges + gauge lights.
My gauges have a common ground wire with the gauge lights.

This doesn't make sense to me:

The common ground wire of the gauge and gauge lights is connected to the dimmer green ??

Then the gauge power wires should be connected to the ign switched source???

confused

Nothing is connected to the ignition of you want dimmable gauges.
The power and grond are spliced into the 2 wires coming of the switches.
I tried and it works.
I believe the color are white green and blue black. Anyway the color is well described few post above.
Good luck.

Ok thanks, but I understand the connection for the dimmed gauge light.
1) green wire on dimmer switch is a GROUND for all gauge light.
2) blue wire on dimmer goes to the lights for dimmable illumination.

Now regarding the gauge 12V power (which should be switched):
3) how can you connect the gauge 12V wire to the dimmer green wire?
That means variable voltage to the gauge power! thats why Im confused here.

Connect the power to the fuse box. Not the dimmer!
There is pic.

One last thing I promise!

re: 1) green wire for ground.
-My gauge light ground wire is shared with the gauge main ground wire for the whole gauge.

That means the gauge main ground wire cannot be put to the chassis. But will be on the green. Is that correct?

you cannot splice the wire in 2?
Well if it is shared inside, I am afraid that if you connect the GND for the gauge to a variable voltage source ike the dimmer, it might cause the gauges to not work well when you are dimming the lights.
It depends on how the car wiring is done from Mazda and I am not sure how the dimmer is wired.
Sorry.
Someone help here...

thats EXACTLY what I got. Gauges have this coming out of it:

-light source wire
-12V+ wire
-ONE common ground
-signal wire

Hence all this confusion. But now I know I cannot dim it with the Protege dimmer. Its either on or off.

Do you have a pic.
I would like to see the common ground.
I am glad you are using electric gauges.
I f it helps you mone dims but I never dim them.

Hello,

I know, old thread revival...

I am about to install two gauges. Both electrical, lit with LED's. One vacuum, one oil pressure. The Vacuum is very straight forward. The oil pressure (op), however is a little more complicated.

I have five wires coming out of the op gauge, according to the very, very cryptic intructions, the green is the signal from the sensor, the red goes to the ACC???(ignition?), the white goes to the lighting, the black goes to ground and the orange goes directly to the battery...

According to the above and previous pages, I would hook up the white (gauge ligting) to the blue/white wire and the black (Gauge ground) to the green/black wire, correct? Will I have any problems with dimming LED's? And...will I have to use a fuse(s)?

If so, why do I need to hook up a red to the ACC and an orange to the battery? Sorry, new at this stuff and am trying to get this done.

Any help would be greatly appreciated. Thanks!

thanks this worked great!!!!

i just put some gauges in and i've been wantin to do somethin like this. i'll have to get on it once i get back in town

mspeedp5, whats that button on u got on the fuse cover for?
