2000 chevy silverado doesnt attempt to rs

do you have some kind of neutral safety switch wire on the remote start......the systems i use have a BLACK/ white wire that needs to be grounded, or the system wont even attempt to start...also check the brake shutdown, and other shutdown inputs you might have on the system.

Well i just did a viper 560xv last week, and i did not ground any black and white wire. And that was on a chevy too and it started right up. However i noticed the 562t didn't Have the blue status light it has the RED one, so im wondering if i need to hook up the toggle switch and ground the black and white wire, i wonder if the black and white wire only applies to the older models. I do remember grounding the black and white wire on certain avital models.
