How to for real gauges??

[J.bo]

Anyone have a link? Detailed instruction. I did search function and alot of talk but no clear instruction I come across.

Hmmm...how is the factory gauge in the car fake? Just curious. Never heard this before. Sorry if its been asked here 10,000 times

The oil pressure gauge reads the same all the time as long as there is "any" oil pressure.

A real gauge will fluctuate with engine RPM.

You also want to change the amp gauge as well.

Interesting and good to know.
THANKS!

fastblackmerc said it and here is a slightly more technical answer.

In case you want to know how they did it, Ford has been putting an inline resistor on their "Oil Pressure" gauges for years. The resistor paired with an oil pressure switch will always give the same reading so long as there is enough pressure to trigger the pressure switch (~5psi IIRC).

The real oil pressure gauge has no resistor and there is a pressure sending unit in place of the pressure switch and it acts as a pressure dependent variable resistor.

Thanks so much

Thanks....

Was a long day ... starting to install 900sq ft of engineered flooring :eek:

Do you replace just the sender or do you replace the sender and oil pressure gauge?

[Blackened300a]

Do you replace just the sender or do you replace the sender and oil pressure gauge?

Have to do both. I experimented with just changing the sender and the stock gauge had a real slow sweep. It moves constantly with the real gauge and sender.

[Rockettman]

More than half the pictures didn't show up on my computer.
You mention to get the neew meter, but what does the new sending unit look like? Is that part of the package when the new guage is purchased (included in the box)?
Also, how does the new Voltage guage change anything with just changing the guage?

The new sending unit is like a small soup can. Look on the autometer website for a picture.

The sending unit is usually sold separately.

The only reason too change the voltage gauge is so that both gauges will look the same. There are subtle differences between the OEM gauges and the "real" gauges. If you had an OEM and "real" gauge side-by-side you'd see the difference. If you change both gauges to "real" ones no one would be able to tell the difference.

You can see part of the new sending unit in this picture (it's at the top)

The Autometer oil gauge comes with the sender.

With the Crown Vics there was a resistor jumpered across the oil pressure gauge on the instrument panel. You just needed to remove the resistor and install the pressure sender.

With the Autometer gauge?? betcha there is a resistor inside one can remove :banana2:

Thanks for the clarification.

That was the first mod I did over 6 years ago......

Negative. Opened up the gauge and nothing looking like a resistor in there, the wires go directly to the meter movement, which is heavily "damped" to give a very slow response.

[bigmerc'03]

theres nothing wrong with the volt guage it workd fine and almost accurate maybe off a lil save your money and change to a full sweep machanical oil guage

[fastblackmerc]

Search the Autometer website.

Here's a PM that I wrote for one of the other members that asked for my help:

These are the part numbers for the gauges used:
0-100 Oil Pressure: Autometer 4927
Voltmeter: Autometer 4992

First, here is the Autometer Oil Pressure sender installed on the car. It looks like there is a pipe thread adapter to get it to fit and I think it comes with the gauge kit. The ring terminal that the wire attaches to replaces the original harness clip. Just cut it off, strip the wire, and crimp the ring terminal on in it's place.

To remove the Gauge panel from the car, put the car in gear with the engine off and pull the sides of the gauge pod towards the shifter.

http://i9.photobucket.com/albums/a88/illwood/Marauder%20Gauges/GaugePod01.jpg

You will have to lift it up when you get the snap clips undone to remove it the rest of the way.

http://i9.photobucket.com/albums/a88/illwood/Marauder%20Gauges/GaugePod08.jpg

The gauges should be held in place with some aluminum knurled nuts. You can just remove these with your fingers.

http://i9.photobucket.com/albums/a88/illwood/Marauder%20Gauges/GaugePod06.jpg

I cut the wires coming off the gauges leaving most of the length going to the plastic snap connector. And just crimped my new ring terminals and spade connectors to those wires.

http://i9.photobucket.com/albums/a88/illwood/Marauder%20Gauges/GaugePod04.jpg

That one is the oil pressure gauge. As you're looking at the top of the gauge, the black wire is the ground for the LED and the white wire is the +12V (they have the light blue insulated spade connectors in the pictures). The wires that actually run the needle are from left to right (again this is looking at the top of the gauge)
Red w/ Yellow Stripe, Black, White with Red Stripe

The other gauge is the Voltmeter.

http://i9.photobucket.com/albums/a88/illwood/Marauder%20Gauges/GaugePod05.jpg

It has the same black and white wires for the LED and the signal wires from left to right (looking down from the top again)
Red w/ Yellow Stripe, Black

I did end up drilling 4 holes to make it easy for those light blue spade connectors for the LED lighting to come out the back.

Next you just put everything back together. The side clips can be a pain to get into the rectangular slot above the transmission hump.

http://i9.photobucket.com/albums/a88/illwood/Marauder%20Gauges/GaugePod10.jpg

Also, you need to lock the plastic tab that the gauges thread to into the dash under the heater controls otherwise it can flop around.

That should be it. Send me a PM if you have any more questions.

If anyone has an old factory oil pressure gage they are willing to donate for the cause I am willing to test and try to confirm if there is a way to modify the OEM gage to allow it to function/sweep with a new oil pressure sending unit. In addition, I will post pictures with a detailed write-up for others to follow if desired.

**OLD THREAD ALERT**

I'm looking to replace my rally-pac gauges with the same Ultra Lite IIs you did but I have a question. It looks like they are lighted with a non-serviceable LED as I don't see a spot to remove a bulb on them. Is this correct? I really like the "Ford green" glow but I'd like a functioning oil pressure gauge more.

[EDIT] I should add that the main reason I'd be going the Ultra Lite IIs route is because the gauge faces and needles look just like the speedo cluster.

[RF Overlord]

It looks like they are lighted with a non-serviceable LED as I don't see a spot to remove a bulb on them. Is this correct?Yes.

You can also use the Ultra-Lite (not Ultra-Lite II) p/n 4327 and swap over the faceplate and the bulb condom from the OEM gauge. It's kinda fiddly work, but a few people here have done it.

[CityConnection]

Thanks, Overlord. That was what I figured. Unfortunately with my fat fingers I'd screw it up and have two dead gauges on my hands. Ha! I'll get over the color difference especially after I swap out the factory radio for something with a navigation type screen. It's gonna end up looking like the space shuttle in there anyway so what is a few different colored gauges gonna matter?

[tylerdurden2816]

So the volt meter comes stock on the MM working properly, it's only reason for replacement is to keep it matching the new working Oil Pressure Gauge?

[CityConnection]

Yup. The stock volt meter is a real working gauge where as the oil pressure is just an idiot light (if the engine has at least 6psi then the gauge shows 60psi).

Mark Olson figured out a way to make the stock Ford oil pressure gauge real.

This is exactly why I installed a new voltmeter in place of my old one where the cig lighter used to go. When I noticed the difference, I couldn't deal with it.....

Good article but it only covers up to 1998 gauges in a Mustang. Don;t even know if that will work in a Marauder.

The meter match unit is at least $50.00 plus there is a multitude of instructions (19 pages), setup etc.

IMHO... much easier to swap out for the Autometer oil pressure gauge that works.

[massacre]

It was a good solution for his problem in his car, I thought sharing it might help others in some way, or maybe ask Mark if he can configure one for you? Mark is a great guy and very knowledgeable.

Personally I have a mechanical oil pressure gauge that only needs power for the light.
So I don't have a dog in this fight as they say, plenty of people like the electric gauges.
