Auxiliary Guages - Electronic or Mechanical

During a drive over to Iowa yesterday I got the "Check Gauges" signal and noticed the the oil pressure gauge was in the basement. A quick stab at the throttle raised the pressure and the gauge went back to normal. When I got back to town I went straight to NAPA and ordered a new oil pressure sending unit. When I removed the sensor the male plug and female sensor were filled with oil. I cleaned everything up, I have already installed the "T" fitting in the block and it is ready for the oil pressure line or the electronic sensor. Space will be tight but I think electronic sending unit would work. I know the mechanical line will work. I will also likely install a trans temp gauge to monitor the fluid temp in the pan.

The great debate is the type of gauges to install - Mechanical or electronic.

Just was curious on your thoughts.

Re: Auxiliary Guages - Electronic or Mechanical

Nothing better than a mechanical gauge in my book but I'm an old school believer.

Re: Auxiliary Guages - Electronic or Mechanical

That was my initial though but the thought of an oil line into the cabin got me thinking and overthinking....

Re: Auxiliary Guages - Electronic or Mechanical

Wow... no other thoughts on this? Maybe I should move this to a section with more traffic.

Get something that plugs into OBD.

while mechanical might be cool you would need 40 of them to duplicate one scan gauge....something like aerotech would be my choice.

They clear codes and read codes. Set up to 8 parameters that rotate on the display. 1/4 mile. 0-60 all sorts. Choose between about 60 pids.

Re: Auxiliary Guages - Electronic or Mechanical

On the 2004 WJ the oil pressure indicator doesn´t show the real pressure anymore, but only oil pressure high or low. There is no sending unit anymore, but a low pressure switch. The indicator will show 0 or a fixed high pressure reading, but it in fact does the same as a low pressure light.
I would go for an electrical pressure gauge. I like more the idea of wires running through the engine bay area then an oil line.
The OBD connector would not do anything for oil pressure readings, since the 2004 WJ only has the low pressure switch.

That is exactly why I am going with an aux gauge. Wiring is easier to deal with than the hard line for the gauge. The down side of the electric sending unit is limited space. My initial though was mechanical but electric would be much easier to install. More details to follow.

Re: Auxiliary Guages - Electronic or Mechanical

I'm with Rob on the Aerotech but they aren't compatible with WJs unfortunately - I looked at them.

So, although mechanical looks cool, I'd go for electrical.

Re: Auxiliary Guages - Electronic or Mechanical

I am ready to pull the trigger on an Autometer electric gauge. I was concerned about space to mount the 2nd sending unit but after a bit of mental gymnastics I am not worried about it. I think this will be my choice...

I plan on mounting the gauge in this pod:
