actuator

hey guys need ur help!!! i jus got a universal door lock actuator ... im planning to install 2 actuators in a mechanical lock car ... only problem when i hook up one actuator to two relays as shown in the diagrams on 12 volt i keep blowing a fuse ... the actuator works by reversing the polarity i can lock it and reverse again i can unlock it but i have to hold the position of the power or ground to make the actuator hold the  position locked or unlocked ... anwyays i was wondering if u guys have any other easier diagram to hook up 2 reverse polarity actuators and what kind of switch should i use because the car doesnt have any switches to begin w/ ... i mean can i hook up a switch from kragen that works and if so what kind ... i still plan on getting universal power door lock switches tho... jus wondering what kind of switch it  is ... so i need a diagram of door lock actuator reverse polarity locking and unlocking other than those on 12volt cause im really confused ... thanks!!!
