i am installing a valet 554R on my wifes 1997 lexus es 300. If I am understanding this right ? there is a GREEN/ black wire on the secondary harness that will send a negitive pulse every time the remote start is activated. Should I tie this into my factory alarm disarm wire with a relay or is there another way to do it? I was under the impresion I wouldnt have to buy any relays. So I am kind of confused by that?

I reads - Factory Diarm/Special Accessory Output ... so I am guessing it throws a neg pulse when you hit auto start? just my guess

^^^ Yes. You probably will need a relay.
