98 Intrepid oil light flickers at idle when engine hot

I have read there is a TSB (08-36-99) on this problem that I have been experiencing lately. I have purchased the wire terminal/vent p/n



05017800AA mentioned in the TSB and I want to install it myself. I would like to know the location of the oil pressure switch on the
2.7L engine. I have looked under the engine (passenger's side) and I see 3 units. From the firewall towards the front of the car they are: a black one, an orange one and a green one (these are the connectors' colors). I suspect the green one is the oil pressure switch but I'm not sure. If it is the one, how do I remove the switch connector from the switch? Something seems to lock it in place and I can't see the typical plastic tabs. If anyone has experience with this could you please share it. Thanks much, Dan

I am not sure about the location of the oil pressure switch on your engine, but it is a green fitting adjacent to the oil filter on the 3.2L engine. There is probably a place to press the connector to remove it. Here is the TSB you are referring to; consult the factory service manual for more information with graphics.

Dan;

Oil pressure switch connector body is light green in color. 1 wire coming out of it. With the engine off, that wire should be grounded to the chassis. Lock tab is probably facing away from you.

The crank shaft position sensor connector body is black. Don't know off-hand what the orange connector is.
