Evo One programming key bypass. Does not finish step 4.

I had an Evo One install in my 06 trailblazer. I replaced it, and installed it on an 05 GMC Envoy XL. I did a master reset on starter and bypass, using recommended updates. When trying to program with the button pressed, I plug in the six pin connector to get to the blue led, I then plug in the remaining connectors. Turn the key to the on position the blue light go out but no other lights come on. If I turn the key back to the off position the blue light return. I'm only using all wires from the 6 pin connector. The data, the park light, the horn, the brake, and the A1 ignition wires off the 25 pin connector. And antenna and valet button connection. All wires have continuity though connector and wires. Tried a spare Evo One that had on hand, got the same results.
