Need Help Understanding Electrical/Relay Diagram

Hi Everyone,

I am modifying three #53 relays to provide the ability to toggle the two high speed radiator fans and engine compartment fan. I know from previous posts that grounding pin #85 will activate the radiator fans, however I am unclear if it is the same for the engine compartment fan.

Both the radiator fans and engine compartment fans can be jumpered the same way, by connecting pin 87 & 30, so I think it should be the same, but I am hoping someone can clarify if grounding pin 85 will also activate this relay.

One more question, would grounding to the Phone Connector in the center console be the same as grounding to a chassis point?

Thank you!
