Installing an Oil Pressuge Gauge on a 2003 Disco II
11 Attachment(s)
Here is a simple "how to" install an oil pressure gauge on a 2003 Disco II. I went with the oil pressure gauge from Glowshift. http://www.glowshiftdirect.com/tinte...ure-gauge.aspx
If you followed my previous install on "how to install a water temp gauge" then you can wire the two gauges together and use only 2 fuse taps for this whole project. You just need to wire up the two red wires together, the two yellow wires together and the two black wires together. What you need: Extra 18 Gauge Wire (Red, Black, Green, Yellow) Splicing Pliers 3/8" Wire loom Teflon Tape Adapter M20X1.5 to 1/8 NPT 2x "add a circuit" fuse taps 2x 3amp fuses and some wire connectors, Everything else including the oil pressure sender comes with the gauge out of the box. First you need to wire up the gauge. I choose to "add a circuit" into the fuse box. The "add a circuit" connector can be purchased at your local Autoparts store for about $5 each. Dont forget to get some 3amp fuses. The red wire needs to plug into a "switched" 12v source. The black wire needs to be grounded to the vehicle, I chose to ground it to a bolt near the fuse box. The yellow wire needs to plug into an "unswitched" source, meaning a source that has constant 12v power to it when the key is not in the ignition. This is what keeps your lighting settings on the gauge when you turn the vehicle off and back on. Attachment 46691 Here is my fuse box with the tap into the two fuses I chose for the red and yellow wires. Attachment 46692 Here is where I grounded the black wire right under the fuse box. Next run the green wire through the firewall and route it neatly to the sender. I decided to add a wire loom for protection and neatness. Attachment 46693 Attachment 46694 here is the wire routed neatly within the wireloom down to the oil pressure sender. Attachment 46695 I decided to try a different method and tap into a different oil port for installation of the pressure sender (included with the glowshift gauge). After finding out the proper size of the bolt I was tapping into, it was a rather pretty simple and fast install. This is the bolt I removed. Attachment 46696 The oil port I removed the bolt from is very easy to reach from under the truck and you dont have to remove anything to get to it. It is located right underneath and slightly to the left of the stock oil pressure switch/sender. This is the adapter that you need to tap into the port. The size is a M20X1.5 to 1/8 NPT I found mine on ebay. http://cgi.ebay.com/ebaymotors/Senso...item5889a5aa34 Even though the listing says its for 1/8 "PT" it is compatible and screws on nicely. Here is my sender installed and wired up! Attachment 46697 Attachment 46698 Attach your green wire to the "G" post of the sender and add a black ground wire from the pressure sender "WK" post to a good ground source. I grounded it to the battery. I also purchased a universal dual gauge A pillar pod and works and fits nicely! The only thing you lose is the left tweeter. I disconected it, or you can drill small holes in the A pillar pod for the sound to come out. Here it is! Universal Dual Gauge A Pillar Pod This is what my gauges look like! Installed and working! Attachment 46699 Here is a nice 15-16psi at normal operating temp and on idle. (minimum is 10 psi per RAVE) Attachment 46700 ...and here is my temp! Attachment 46701 Hope this write up was helpful.:D |
Very nice, thank you.

The M20x1.5 > 1/8" adapter is the slick way to mount the pressure sending unit. I'm ditching the stainless cable setup as I was thinking of doing before. I was curious if one of those other large bolts on the front cover would unscrew and you could do this. Thanks for doing my homework! I found the "add a circuit fuses at AutoZone for $6.99 each.
Nice setup! You beat me to the cool write up. Maybe I will show my digital gauge for kicks. Here is what I did after much research to make installing the presure sensor easy and you dont have to wait 3/4 days for the M20x1.5 adaptor to show up in the mail from eBay.

Nice setup! |
Anyone know whether the front cover on the 4.0L engines is the same as on the 4.6L? I'm just wondering whether the M20X1.5 to 1/8 NPT adapter will work on the older DII's also...

Yes they are the same, but.... they have oil coolers that use those ports. So either disconnect your oil cooler (I don't think so) or fashion a T for the sensor - this is the part that becomes tricky. The 2003/2004 Discos do not have oil coolers, that is why they have those spare ports.

I guess it's back to planning to do it as described here: http://www.landroverclubvi.com/oil-gauge.html |
I'm using a M12 adapter on the spare port above the stock sensor, then some 1/8 nylon oil gauge hose you get at Advance and Autozone to plumb to the sensor. I will see if I can get my lazy ass to post some pictures, but it is a pretty simple setup and avoids complex T's and extension hoses.

Photo #1: oil pressure sending unit with the 1/8 nylon tubing kit from Advance.
Photo #2: M12 adapter and one end of the nylon tubing attached. I used a spare piece of black tubing slipped over the 1/8 nylon tubing for protection. Photo #3: My test gauge attached to the other end of the 1/8 tubing. Plan A was to use a mechanical oil gauge and so I used a long piece of tubing, I have since changed my mind and got an electrical gauge. Photo #4: I want to make a bracket to hold the sending unit and attach it to one of the 2 bolts, or use the spare hole. The thick cable is the battery earth on the alternator bracket. Photo #5: I made a bracket for sender unit, I bent a piece of aluminum into an L and drilled 2 holes and bolted it on with the battery earth bolt. |
