How do you hook up door locks in 2004 Toyota Highlander?

Question

There is the Purple unlock wire, Gray lock wire, and the brown wire.  In order to lock the vehicle it says you need to break the brown wire, and in order to unlock the vehicle, you need to send a pulse the brown in addition to the purple.  I was looking around and wirecolor says to use a relay.  I hooked the relay up to break the brown wire using the door lock to pulse the relay  and isolated the brown wire with a 3 amp diode.  The unlock works perfect, but in order to lock i need to press it 3 times in order for it to lock.  does anyone know the proper way to set this up as I must have something wrong

I had everything exact execpt for the lock detection connection hooked up to 87 not 87a.  I was going to try 87a that but didn't get a chance to last night.  I will do in shortly and let you know how it works
