I recently bought a couple of gauges for my 98 Integra and having a little trouble figuring out how to install them.
Oil TEMP Gauge
From what I see the oil temp gauge has four wires coming out of it.
Black: is to be engine ground (where???)
Red & Orange: I think are suppose to be connected to the iginition somehow
Green: is to be connected to the sensor
Also, The sensor has two wires coming out the top of it, one I think is suppose to be connected to the green wire from the gauge and the other is be grounded but where?? Also where do I put the temp sensor???
Water TEMP Gauge
Everythings pretty much the same, four wires go to the same places, but where do I place the sensor??
Air/Fuel Ratio Gauge
Same thing, black to be grounded, but where??? Red and Orange to be connected to the iginition somehow?? and Green is to the 02 sensor. But which sensor the one on the cat-converter or my headers and which wire on the 02 is the signal and which is the ground.
So, if anyone who has installed their own gauges can help me out it would be greatly appreciated. thanks

 

Oil Temp:
The black goes to any common chassis ground. Any unpainted metal surface will do.
The red goes to constant power.
The orange probably goes to switched ignition power.
The green goes to the sensor.
If you tee off the oil pressure sender at the back of the block, you can fit the oil temp sensor in there with a 1/4" pipe thread joint.

Water temp:
I have no idea where you would place the sensor. I would assume somewhere where coolant flows...:thinking:

A/F ratio:
You want the primary O2 sensor. That is the one upstream of the catalytic element. The white wire will be sliced into and the green wire connected.

I think you are way over your head with this project. What is the need for all these virtually pointless gauges again?

 

Unless you have a wide band O2 sensor and gauge, the air/fuel ratio gauge will be useless. The range on the standard O2 sensors is less than 1 volt. They operate by jumping back and forth betwee too rich and too lean. So all you will get is a gauge flip flopping between green and red. You may mess up your O2 sensor wires as well by splicing into them. Not worth it.

 

constant power where?
iginition power switch where?

DANG you guys know how to put a person down......

That will help you with the wire locations.

 

thanks for all the help guys.... i was able to install the gauges very smoothly....dang, do they look oh so beautiful whenever i start the car........
