help with programming KOA

Question

i have a 2009 toyota tundra that i am installing crimestopper rs1-g5 with fortin KOA. the CS unit is working properly, and will remotely start with a key in ignition, however, i cannot get the KOA to read my key. i have double checked all my wiring, but it won't even flash, no matter what combination i put in my 2 connections. i've tried reversing my rx and tx, in case i misread, but no, still no change. my green wire to key sense has a positive load on it at all times, i don't think this is correct. the keysense wire loses its load when a key is installed, so i'm confused how that is meant to tell the ecm the key is in, when it is not. some logical help would be appreciated, instead of repeating ourselves "Hold button, plug in, put in key and wait." i know, i've tried. for days. let's get real, and help me out please. thanks.
