RB20DET Oil pressure sensor

[Armysweitzer20]

So i have everything working properly, I see a second wire coming from the sender. Just wondering what it was?

oil pressure gauge

[Armysweitzer20]

i already have one hooked up to the oil pressure gauge and it works...

then what are you worrying about? just tape off the 2nd wire.

[Armysweitzer20]

because thats a dumb idea

[Armysweitzer20]

anyone?

low oil pressure warning light

The yellow wire is for the oil pressure warning light in the cluster. The blue wire is used for the oil pressure gauge in the cluster.

[Armysweitzer20]

excellent, thank you. Is this wired directly to the cluster or on the ecu?

[integra7]

the oil pressure warning light is wired directly to the cluster through the lower harness (use existing wire).

you can only use the oil pressure gauge wire if you have the skyline cluster. the ka cluster does not have an oil pressurer gauge. if you have the skyline cluster, you will have to run the blue wire directly to cluster yourself.

but you said you already have an oil pressure gauge hooked up, so does that mean you hooked up the blue wire? if so, why are you asking this question and what did you hook it up to? or you mean you hooked up the blue wire to an aftermarket oil pressure gauge (which will not give you correct readings)?

[Armysweitzer20]

well i had the oil pressure wired to my r32 cluster, I must not have the warning hooked up. For an aftermarket gauge i need the corresponding sensor correct (aka wont work with the stock sensor)

correct
