Installed all wires and double checked rx and tx. Step 5 does not flash quickly, only solid after holding button down. Have tried reflashing multiple times. Will start with key in barrel with rfk441.

Please flash firmware 79.41 into the unit, re program it to the car and re test.
It's is at 79.65. Is that not correct? The newest update? That's what was suggested. Thanks
Sometimes older cars will need older firmware to work properly.
Gotcha. I will try. Thank you
I reflashed the unit to 79.41, led still stays red on bypass copying step. Never flashes 10 times
If it does not flash then you would need to verify your lt.blue and lt.blue/black wires.
I know I am correct on those right now and continuity is there(good connection). But I sort of remember another install and those wires being labeled backward in the diagram. Could that be possible?
You can try flipping them, wont hurt anything to try.

 

If that doesnt work I would suggest calling technical support when you are with the evo and the vehicle.
