[QUOTE="jrz126, post: 1107050, member: 556466"] Yes and no...it depends on if you are using the normally closed connection or not. (pin 30 is connected to 87A until power is applied to the coil, once power is applied, pin 30 will be connected to pin 87) Lets say you have a red and green light. pin 30 is connected to +12V, the + of the red light is connected to pin87A and the + of the green light is connected to pin 87, (and the -'s for the lights are grounded.) with the coil deenergized, the red light will be on and green will be off. apply voltage to the coil, and then the green light will be on and the red will go off. It wont work if you swap pins 30 and 87. In your case though, it would work just fine. [/QUOTE]
