You can wire in the electrical to your clock or stereo harness. I find the clock easier and cleaner. On the GD's just pull straight up on the clock dash pod. The clock side of the harness is already marked for ground, ignition, illumination, etc... For the sensor, there are a couple oil gally plugs on the block that you can thread your sensor into. Depending on the gauge, it might come with an adapter that allows you to directly thread into the gally plug. There's one on top of the block on the passenger side that is easy to get to. Alternatively, you can get a sandwich adapter that goes above your oil filter. I've never seen one that doesn't eventually leak, but it works for some people. You can thread your gauge sensor into that.
sandwich adapters suck! not only do they always leak; u have to run wires a lot longer! Also when u get ur gauge make sure u get an oil galley plug to thread ur sensor into, they dont come with the gauge.
The oil gallery plug on the passenger side top of the engine that runs by the recirc tube is the easiest to get to. You'll need to buy an oil gallery plug adapter on eBay or wherever that has NPT threads for most oil pressure sending units marketed in the U.S. I'd stay away from the Autometer gauges for this one since the sending units they provide are way bigger than necessary and make for a very tight fit. Also, get a gauge with an electrical sending unit vs. using the ones with the little tube that are considered mechanical gauges. The little plastic tubes, even when substituted with copper tubes almost always end up leaking somewhere.
Yea, I spent more on a braided extension line from that galley plug to the sender than I did on the prosport electrical oil pressure gauge, sender, and galley plug combined.... was no way to tighten the sender to the plug without extending it upwards
I threaded on an elbow and put the sending unit off to the side on my car. Tight fit. Autometer sending unit FTL. I hope I never have to change that sending unit. If I do...I'm doing TGV deletes and adding a smooth intake tube while I'm at it. Nate and I spent 6 hrs installing the sending unit as a result of everything that domino'd wrong in the process. Not a fun night. Hindsight would have had me doing what you did and extending a threaded port and mounting the sending unit remotely.
On mine we put in a 'T' piece and installed the sender unit alongside the stock one at the front of the engine. That left the rear one available for the oil temperature.
Yeah, while the galley plug may be the easiest to get to, most sending units aren't going to fit, especially on the 2.5L cars, which have even less room there than the 2.0L's. However, installing in this location is probably the best, but is going to be a bit of a PITA to install, and you may want to plan for a relocation kit (although those can be cheap). As mentioned previously, sandwich adapters are easy to install, but you may end up running additional line that has a chance of leaking.
this is an old thread but i didnt want to start a new one. im going to be getting a boost gauge and electrical oil pressure gauge and im wondering whats a good brand of gauge or what people on here like. i was leaning toward the prosport standard series, also has anyone had any luck with this gauge pod? thanks. http://www.fastwrx.com/dugadabe.html
