installing standalone evo all (EVO-CHART5) with T harness on 2007 dodge durango. I have made the connections purple from T to Green/ Red (a18), yellow from T to yellow(a1), plugged T harness behind key switch. Used flash link 2 and selected options c1 for lock 3 times to start. I plug in black plug to evo all while holding in the button and release on blue, plug all connectors in and when i turn the key on the blue light goes off. I have 12vdc on the yellow wire (a1). Turn the key off and blue light comes back on. I have verified my all my connections. I even did a master reset, downloaded the latest firmware etc. what else should i do?? I have installed 4 of these so far and i have never had this issue with the others.
