Oil Level Sender

[whysimon]

What are you guys doing for this. I can't stand seeing the oil light on my check panel.

awesome!

Why not just run a wire to the connector?

I used an e34 engine/harness which has the sensor and the wiring for it. Since you have the e34 oil pan, and I'm assuming have a sensor in there, why not just wire it up? I'm not sure how it's wired, I'm guessing just a ground and a signal wire to the x20. That would be simple to do.

get the oil sensor from the e34 oil pan.

looking at the engine with the sensor's plug looking up. pins left to right are as follows
left(3) - ground (engine mount ground okay)
middle(2) - dynamic - pin 10 of your C101
right(1) - static - pin 2 of your C101.

you have to check what static and dynamic pins are for eta cars. all "i" cars wire as above and you'll have a working OLS.

good to know. I'll do that

It's pin 2 and pin 15 for early cars with a square c101:

Thanks very much. Any chance anybody has one?

[isolatos]

this didnt work for me. any other ideas?

easiest way is to just cut the connector and wire out of the harness when you take your c101 plug. Then just install sensor, run a ground, call it a day.

I wired the plug to my c101 and the light stayed on??

you have the signal wires backwards... reverse them. or add oil???

[dranttna]

that is good to know. does the dme look at either oil level or pressure, or are they straight to the gauges?

[BeirBrennerE30]

oil pressure goes straight to the cluster and the oil level goes stright to the check panel. Nothing else uses them.

I will recheck this afternoon. Thanks
