Tan, you do not need a relay to double pulse your 2004 Toyota 4Runner door locks. Simple wire you the lock and unlock wires then program your DEI remote starter to send out a double pulse. Your DEI remote starter installation manual should have instructions on how to set up a double pulse output on your door lock system. Hope this helps. Good luck with your 2004 Toyota Corolla remote start installation.
