Gauge installation

[pilfflip]

I just got an autometer air/fuel ratio gauge and oil pressure gauge. How difficult are these to install?

I vaguely remember seeing a sensor that you can get that plugs into the oil pan as a direct replacement for the plug and it reads the pressure for the purpose of wiring in a gauge. Is there another method for this?

...and the Ait Fuel ration, I don't even know where the reading for this would go. Any help would be appreciated

Wow, I was just going to make a thread on gauges, but it was going to be about mounting them.

Search for a thread by Pat, he had a nice little adaptor for the oil pressure that goes on the filter. Did you get an electrical oil pressure gauge? I would never want to run an oil line into the car.

For the AFR you need to tap into the ecu, but I remember someone saying that if you cut that wire the ecu will not be able to read the signal. I have a factor print out of the ecu for the 95, I will look up the ego wire later and post it.

These will need power, so just use vampir clips and run them off the radio harness. The AFR will have two wires for power, and one signal. The oil pressure should have two power wires and then two wires for the light. I was albe to use the radio dim wire so that my gauges only light up when I have the car lights turned on.

i wouldn't just tape the illumination wire to power the lighting, i'd rather use it to throw a relay to illuminate all the gauges at once. run the gauge illumination through the fusebox.

i like clean installs like that... also very safe.

dont worry, ill help ya out......

Okay, after i started thinking about and I got to the gauges I had a couple of those "duh" kind of thoughts like my brother has sometimes, it kind of made me feel dumb.

The oil pressure gauge isn't an electrical one, there's an oil line that's ran into the gauge itself with compression fittings on each end, i also got a T that way I can T into the oil pressure sensor on that block, anyone know where that is?

Then the AFR gauge is just as you said Subie, but i was thinking about it and couldn't I tap into the O2 sensor signal that's going into the ECU to get my reading?

Now all I need to do is find a way to wire up the power for a selective illumination...:/

your killin me.......its on top of the block up front...you know where my EA82 oil sender is on the EJ22 in my 86' GL wagon................

i wouldnt cut the wire from the o2 sensor, i would "T" into it, at least that what i would try first. anywhere between the o2 sensor and the ECU "should" work...but you know how i get when i say.. "should"....


and we should probably get a new oil pressure line...that plastic line looks like crap, just like the kind of car it came off of.......
