Can anyone tell me which pin in the firewall wiring harness connector
is destined for the oil level light ?

The motor in this '94 ES300 was replaced with 1MZFE from a Camry
and there is no oil level sensor on the new motor. Additionally, there
is no connector on the wiring harness (which must have come with
the other motor), so I need to connect the pin in the harness to ground,
but I don't know which pin it is. Does anyone know or have a service
manual for that year model (94) ES300 that would have the pinout ?

Thanks !

This is a very technical question catered to the Lexus experts in the Maintenance forum, so I'm moving your post there

I will try to take a look at the wiring diagram tomarrow, but in the mean time, why not just pull the bulb out of the cluster? All you're trying to do is eliminate the light correct? So either grounding the wire or removing the bulb itself would work fine for your purpose. Personally, removing the bulb is easier.

yeah, but the light wont function if he ever needs it.

according to JPI, you should swap an oil pan from a lexus 1MZ??(i think thats the motor)

Thanks for the input folks. Yes, RTCamaroSS, was trying to determine which was
the simpler approach, but was concerned about any possible "light out" errors that
removing the bulb would send to computer controls.

Given that the oil pan approach would involve (at minimum) :
Removval/replacement of oil level sensor (maybe whole 2nd pan)
Removal/Replacement of existing wiring harness

The more direct approach seems to be to eliminate the function.
(and to check the oil when filling the tank) which is a practice of mine,
regardless of the oil level light.

Thanks and if you can tell me the pin, that would be awesome!!!

It wont cause any errors in the computer if that bulb is out. It just simply wont light up. This is the simplest approach to your problem. Unless you want to put the correct pan on it, and actually run the sensor. Which would require running the harness, swapping pans, and some wiring work. Either way, i will try to look it up at work tomarrow, if i have time.
