I am going to use the Greddy oil pressure gauge on my 95 LS.

I removed the factory oil pressure dummy light switch, am I going to have problems with the cluster oil light on or vtec not engaging because it thinks theres no oil pressure???

I plan on leaving the factory oil pressure switch disconnected... Has anyone had experience doing this???

Nope, you won't have any problems at all.

The stock dummy light is a one-wire ground signal. When the oil pressure gets to a very low level, it grounds and sends the signal to the dash.

It won't hurt anything taking it off completely.
