I have just installed an ultrastart as2250 in a 2000 silverado.  Everything is working except keyless.  I am getting nothing from my lock unlock wires. I just wanted someone to talk me through where the lock unlock wires should go just to make sure I did it right.

Then you'll need to reverse the polarity with a relay. You didnt mention if it had factory keyless or not. If not you will have to do the reversal rest at ground wiring. I think there is a diagram here showing that.
