I just finished wiring my zex dry system with a window switch and WOT switch with a relay. On the relay I have the white from the window switch to the 86 post, the ground to the 87 post, the power to the 85 post and the solenoid to the 30 post. The way zex says to connect it. The question is... I have continuous power to the 30 pole of the solenoid. Is that normal and will it draw power from the battery??
