  Got this relay and I need to figure out which prong is 30,87,86, and 85. I have continuity at the top right prong to bottom left prong. And I also have continuity at top left with bottom left. Confused as to how I would wire up this relay. This post has been edited by bccentaur3: Dec 15, 2015 - 1:43 PM -------------------- 98 Celica gt red- totaled deer

There's generally 2 kinds of relays, normally open (the contacts are not connected inside without power) and normally closed (the contacts are connected inside until you apply power). That sounds like a normally closed relay, you can see what pins are what if you have an ohm meter. The two contact legs of the relay should have low resistance (~.1 ohm) and the coil legs of the relay should have some more resistance but the value varies depending on the relay. Some relays have a diode on the coil side to prevent any inductive spikes from feeding back into the control circuit when the relay is applied or released. That will cause you to see an open circuit when checked one way and the correct resistance when checked the other way.
