I have the above relay with pins numbered 85, 15,D+61, and 87. I understand how to install a relay but did not know which two of the pins controlled the coil. Could someone help? I want to install an aux. condensor cooling fan inorder to lower ac temp. Any ideas as to how I can automatically energize coil to close contacts and supply power to yet to be installed fan. I want to keep it simple under the hood not in the dash. I was thinking about tapping one side of the pressure switch relay on the air dryer as that is what closes to start ac compressor. I didn't know it the voltage drop with the new relay added would stop both from working. Any suggestions. This way my new fan would kick on when ac compressor is running.

This is no normal Relay it was designed for a special purpose.

Are you sure you want to use this one?

Yes,

thanks for all you help. I have decided to get a more basic relay for the job. what do you think of my method for pulling power to the relay (control coil circuit only) from my ac pressure switch on the dryer .

Just tie the coil of the relay across the output of the Fan relay.

Then everything will come on as it is designed to.
