Good afternoon, I will assume you have a 4 dooro stratus with the 2.7 liter engine. If its not then let me know otherwise. Here is the info you requested:
The engine oil pressure switch is located on the right side of the engine block (the firewall side). You will have to gain access to it from underneath the vehicle. The switch screws into the engine main oil gallery. The normally closed switch provides an input through a single wire to the low pressure indicator light on the instrument cluster.
If this answers your question then press ACCEPT. If you need more help then let me know. Thanks
