Boost and Oil Pressure Gauge Wiring and Install

Well my GF got me a couple of gagues for Christmas to get me started. She got me Oil Pressure and Boost. They are electric gauges from Prosport. I know some have had issues and would prefer not to use prosport but I like them because they are affordable for a daily driver who likes to thrash on his car occasionally and they come in Blue, which i prefer over our red.
To the point now haha. I like to keep things clean and hidden to the best of my ability when I have the time. I was searching for people who installed the oil pressure gauges and came across a link on nazioc and really like how the install was wired up for his gagues. Here is the link:

He wired up his Defi Controller box this way and I was wondering if anyone new if our wiring setup was the same or if anyone had the wiring diagram for what wire could be used for the 12v ignition.
I like this method so when i have acc on, it won't have any warning buzzers. Or if you guys have a similar method and no of the other wires, i appreciate any insight. I personally don't like the fuse box tie ins and the fuse's with the wire taps either.
Thanks guys!

Side note also, anyone who has done the Oil Pressure install, did you use the galley plug under the intercooler? Or Sandwich plate?
Pics are welcome as well!

I already ordered the pillar pods from 08subie as well and would do my best to try a write up to do all of this, so thanks for the help again!

10rex, i looked under the intercooler and it looked impossible to get to without removing a million other wires and hoses.
how much needs to be moved and how much longer did it take cuz i would love to use this location too.

when you installed the the oil pressure sender, was there enough room to fit the sender or did you use a relocation kit?
also would you mind taking a pic for me? thanks a lot!

they show a video of it installing on their website, or if you go to youtube check out prosport.

it is kind of under the very back of the intake manifold, i am out looking around at mine right now kind of. trying to run some wires for the gauges, so when i get the a pillar from 08subie i will just have to plug them in.

i think i read it is an 8mm hex head.
if you have the new one to go in already, you can double check the measurement.

I got most of my wires run this weekend for this and I tried my best to hide the wires and attach them to the factory stereo wires, I guess I didn't find the right wire from the Heater controls, not sure which one would send the power for the 12 volt ignition.
If anyone knows I would be all ears, but the gauges light up and do their ceremony like they should.
Gonne order the oil pressure relocation kit shortly and then set it up and run the two wired to it and I will be good to roll.

any tips on keeping that crap out of the way to be able to even get to the galley plug?

how did you manage to get that bad boy out?

Calling 10Rex, we need your assistance lol.

do you happen to have a little snap shot of your relocation kit installed?

did you get the galley plug from Subaru? The new one with the right hole in it?

is that tab in your pic holding a coolant line?
what if the tab were squeezed with pliers and rotated out of the way? Do you think it is possible?

In order to install the one to install the sender was a pain. Since that 'evil' piece go in our way and after an hour or so of fighting we tried another way. With the MadDad relocating kit this brass piece came with it that plugs into the galley plug and the braided line. This piece was 11mm. So we put this piece into the galley plug and then used a deep socket socket that cleared the threads to tighten it into the plug location.
could you elaborate on this some? i am a little confused with how you got the prosport galley plug and was there a reason you got the plug and not the whole relocation kit from them?

interesting, so if i am getting you right, the brass fitting from the mad dad kit has a piece on it that your 11mm socket could be attached to and then threaded in. makes sense now.
what is that evil piece that is getting in the way?

awesome pic, i tried running wires through that hole and couldn't get anywhere. how did you get wires through there?
it felt like i kept hitting a wall of sorts,

i have my wires running through a hole i punched in the large grommet that has a big harness in it similar to the large one on the right of your pic. i am gonna try that hole again when i install the rest of my wires and other gauges.

hmmm, i like the wires as hidden as possible and this could be the ticket possibly. that grommet gave me quite a bit of sh*t.

yes they do, it is a tight fit and you will prolly need a relocation kit to fit the sender in there.
someone else asked me about it and they needed a relocation kit.

well if you take off that alternator cover you should have a good idea of how much room you would have.
that should only take a minute. there may be more room or less, i personally haven't looked there.
