Can any one please let me know what this is? It is located near the rats nest. Its a small cylinder object. The one on the picture has some cable or wire going out of it. I found this pic while browsing through some threads. I remembered seeing it near my rats nest also but mine didint have a wire coming out of it. I was cluelless as to what its purpose was. Does anyone know what it is, where does it hook up to, its purpose, and if it is necessary?? Please any help will be appreciated. Thanks.

 

its a capacitor that smooths out the pulses to the oil pressure gauge

 

Thanks. Do you know if its necessary? And if so, where could i get a replacement? and where does that wire go to/connect?
