Oil Pressure(not what you think!READ!!)

Joefishizzle · 03-26-2012, 10:13 PM

hey guys ive looked everywhere for this simple yet frustrating thing. well my oil pressure gauge doesnt work. go figure. now my question is not to ask why its not working.

i found the oil pressure sending unit. however there is no wire or anything going to it. my question is what type of connector goes on it?(push, soilder, connector?) and also where in the harness does this wire run?

Thanks

Oh and 87 MK3 7MGE N/A 5 SPEED. thanks guys

It's a single wire connector that slides onto the nipple of the pressure sending unit. Ive used a female spade connector in the past to fix a missing connector. As for where in the harness it goes, I know that it is bunched with the wiring thqt goes to the thermostat housing; beyond that, I'm not sure.

Do you think by chance you have a picture? I've looked everywhere and can't find a spot for the terminal to hook up. I've felt for broken metal maybe to see if it broke off but it's all smooth. And by chance is the wire yellow with a black stripe? That's a broken hanging wire I found near the dizzy harness like you mentioned. Thanks for the help

Look in the MKIII FAQ section. here's a thread on 7M sensor locations which shows the oil pressure sensor, connector and weather boot. If memory serves me correctly the wire (it's a single wire) is yellow with either a black stripe or maybe a red stripe. It runs in the harness which runs over the engine behind the timing belt connector.

Thanks cre,
I've located the wire. I know the sensor on my motor is just under the exhaust manifold to side of the filter base. However, as stated before I can't find a terminal end for a connector to go one. Judging by the picture from the replacement part on autozones website mine looks nothing like it. Mine maybe OEM however.
I was just wondering if anyone had a picture so maybe I could see and go from there. I really don't wanna spend 55 dollars on a replacement if I don't have too.

The end that the harness connector attaches to is like a nail head. A "T" from the side. The connector slides on it sideways. No idea what the autozone one looks like, but if you're looking at their website you're most likely not looking at an actual picture of the part.

Also of note is that the JDM sensor is smaller. The USDM "can" is about 2" in diameter and the JDM is about 1". They're not cross compatible.
