Default Check Gauges Light/ Missing Oil Level Sensor

At the time of my supercharger installation In my 1990 (L98 Auto), the mechanic had removed the oil level sensor in the oil pan when installing the return oil feed from the supercharger. This caused the Check Gauges light to come on that has stayed ON ever since.

One of the forum members had advised that it should have a plug with a Pink (going to the CCM) and Black (Ground) wire and shorting them should turn the light off.

My problem is that I couldn't find any plugs hanging in the vicinity with a Pink and Black wire. Not sure if the mechanic completely removed it or what.

Where do I check it? How do I trace it to the CCM?

Your help is greatly appreciated.

I ran w/o that sensor for awhile until I got around to replacing it. If it's like my '95, all you have to do jump across the two wires as you already know. If your mechanic did cut the plug off, the wires should still be nearby in the harness, taped up or something. Mine didn't make the check gauges light come on but instead the separate 'oil level low' light. Perhaps it's different on the earlier cars.

I believe it is indeed different on the earlier models. There is no "Oil Level Low" light on my '90....the Check Gauges light covers the low oil level indication in addition to maybe others.

OK...I guess I need to look harder for the cut off or taped up harness.

I would let you know how it goes... Thanks for your help.
