No, tried and tugged on the existing ribbon wire and it must be secured. What I am thinking is this. If you look at the thermostat you see the 4 wire plug. 2 blue 1 red and 1 black. That's the wires I need to get to the control box. That there is my 12v+, 12v- and my 2 blue furnace wires. I don't have any choice but to do a partial disassembly inside and get those wires up. I will also need the 12v+ constant wires. That I will have to figure out as I don't have that. I will have to run that from the 12V distribution block.
