Oil level light

So I've had this MR2 for going on 12 years... And for those years it's had a dash light telling me my oil level is low. This 3sgte does NOT have a sensor for that. I've checked.(the guy before me put in the jdm engine so I assume he did it with a "close enough" frame of mind, at least that's the way everything else has looked so why not) I'd finally like to know how to get that light to not come on and I never wanna see it again... Preferably without removing the cluster and crushing the stupid bulb. Anyone know how I could wire it to not throw that light?

Everyone likes pictures so here is one of it... (Showing my newly installed omori boost gauge too I guess since it's just a oil level light...)
And a good pic of her for no good reason.

Find the plug end if he didn't cut it off and bridge the two wires together.
Otherwise, way easier to pull cluster and remove the bulb IMO.

I can't tell you where it receives the sensor data but my gen 3 has a working instrument. I once dumped all my oil following a turbo line break and the light came on with approx. 2.5l in the sump. Guessing there is a level switch about 1/4 way up sump.

Mine is a gen 2. And I can assure you there are no wires or plugs coming from my oilpan so it's not got the sensor hidden or otherwise. I just want a picture or idea on where to splice some wires to make that light leave me alone.

I appreciate the input though. A sensor would be cool if it worked but I know it's not there so I just want it to stop yelling at me. It's like my kid crying because I didn't feed the pony that doesn't exist.... "You're being irrational! We don't even have a PONY!" Kinda like that.... Silly 2 year olds....

from a Gen 2 USDM
as long as the PO didn't cut the cable, you should be able to find the sensor plug (assuming he used his original wiring harness)

That is perfect thank you! I really appreciate the picture. Seems like a small thing but knowing where that wire "should" be makes finding it easier lol.

GEN3 doesn't have a level sensor. The oil pressure light symbol is different to the oil level sensor symbol. You would have seen the pressure switch light active when you dropped your oil.
The GEN2 3SGTE for the USDM market and the GEN2 3SGE for the NZ market and maybe the UK/Euro market had an oil level sensor in the steel sump pan. The JDM engine never had it so like others have said the plug can be bridged or the wires bridged if it was cut off.

Near the bottom of this post it shows the sensor and the light for a New Zealand New SW20.

I appreciate the clarification. Mine is a JDM gen2... With a USDM wiring harness. The sensor is quite obvious when looking at the pan and mine is steel seeing as how it's dented pretty good. I'll sneak a pic in front if the right back wheel... I've been in there a few times so I don't know if I'll find the damn sensor connector.

If the connector is still there the wiring comes off the back of the engine under the intake manifold where the alternator wire goes into the main harness. It appears to have a second plug between the harness join and the level sensor connector.

If you are able to access the 93 SW20 wiring diagram document it is on page 25 and noted as E10. This will help you locate the potential position of the plug or wire.
