yes, I considered it....but I wanted oil pressure, and odbII does not display it......so I put a sandwich on the oil filter and wired the tube up through firewall (sharing the port with the hvac temperature wire), and I think I am going to add the gauge to the dash ......i need to drill a 2 1/16hole, and I think that might be a great place for it.
that was a consideration.....the copper wire/tube was 72" long, though. Since the oil filter area is about as far away from the driver seat area as you could get in the engine, the tube is not going to be long enough to route and wire up to the a-pillar......
I think this is common among many manufacturers......if you want the oil pressure reading, you have to add the sensor yourself.

Okay, i ran out to ace hardware and bought a hole-saw drill bit that was close to what the installation instructions recommended (2 1/16" was the recommendation, closest ACE hardware had was 2")......so I drilled the 2" hole and then used a grinding 'bit' to make the hole a little bigger.....Keep us posted with what you come up with.......mounting pics and oil pressure reading info would be great. Members, myself included, would like to know.
Mechanical gauges (oil/water, pressure/temp) do pose mounting limitations.......that's why I mounted electrical pressure/temp gauges in some previously owned vehicles.
I guess Honda doesn't think oil pressure is important enough for most OBD-II readers to display.

Then again.. your CRV is an older model anway. I would have gone for a digital gauge.. but that's just the electrical engineer + aesthetics in me.i wanted something simple.....and yea, its almost an 18 year old car, but I didn't pay a lot for it. I wanted a 5 speed AWD, and that is becoming tough to find unless you get a subaru or maybe a model or two of jeep.Good job.
Looks pretty "old school" on a CRV dash though.
yes, mobile 1 full syn 5W30........yea, the oil pressure switch for dummy light might have worked, but I already had a sandwich on the filter, so now i have both the actual pressure reading and the oil light works too......Ditto on good job.
I'm thinking there probably is a factory electrical oil pressure sensor somewhere on the motor.......something turns the oil light off, right? Maybe Honda just uses some minimum oil pressure number for the dash warning light and calls it good from there.?♂
Are those numbers with 5W30?
A word to the wise: I installed a mechanical oil pressure gauge (with nylon tube) in an old 1969 Datsun. One day, on the way to K-Mart, the tube broke at the engine block. By the time I got to K-Mart, about 3 miles away, the oil had been all pumped out of the car onto the ground and all over the engine compartment. Fortunately, I had the old electrical sending unit in the glovebox. I bought some Vice-Grips and a gallon of oil in the store and was able to replace the sending unit, add oil, and drive home. I'm really glad the other end of the tube didn't break or I'd have a gallon of oil on the floor by my feet.
I upgraded to copper tubing, although I hear it can get hot and break over time, too. I tried to route it away from the exhaust as much as possible. all the common auto parts stores sell the EQUUS copper or nylon tubing separately- my kit came with Nylon. I think stainless braided is the best, but i didn't want to drop $50 or whatever it costs for stainless that was 6' long.
There are advantages to electrical gauges. IIRC, I read at the AutoMeter site a long time ago that one (electrical or mechanical) is as accurate as the other.
