Activating this relay is done with the coil (terminals #85 and #86). For auto security applications there are numerous features which require the use of a relay such as Starter Kill, Circuit Isolation, Trigger Inversion, and Trunk Release. The 8617 relay is capable of handling 40A maximum across its normally open contacts and 30A maximum across its normally closed contacts.
