they do not make either part of the connector so unless you get one from a junk/salvage yard your choices are limited to replacing the programmer or removing and bypassing the connector.
Yes its as simple as running 1/8 vacuum line between the two "ends" but if you notive in the pic that not all the colors stay the same so pay attention to what the new color is inside the programmer. Do it one line at a time and you will be fine. As a test, if 'lower' is working in your car, use a peive of vacuum hose to and connect the black/navy tube on the left to the white line coming out of the programmer. Selecting 'lower' should turn on your vents then. So you will need to only cut the white and black lines.
No you do not need to take you dash apart. Remove the glovebox (4 screws). Remove the hush panel (4 screws).
On the programmer cut the vacuum lines near the connector.
Test each line that is heading to the drivers side and make sure it holds vacuum and redirects the air properly as listed.
Green line puts air out the defrosters with a little out the bottom.
White line put air out the bottom with a little out the defrosters
Neither white nor green will produce a little air out of both defrosters and lower
Black line (looks like navy to me) puts air out of the vents
Orange line close the outside air (turns on recirc) You'll fell even more air blow.
There'* a plastic lever on the bottom of the programmer; on the left side of the lever push the white pin in that secures this lever to a screw and it will practically fall off, unhook it from the porogrammer.
Remove the large wire connector going into the programmer.
On the top you'll see wires coming out of the programmer; follow them up to where they go into another box and remove that connector (pull straight up).
Now remove the 2 screws holding the programmer in place.
Slide it down to the floor and pull it out.
There are only tabs holding the cover on, open the unit up and again, cut the vacuum lines near the connector and remove the connector. Keep the connector handy, you'll need to to see which color turns into which color in case its not the same as my pic.
What I did was to put a peice of the tube in the end of the new vacuum line to identify the line color, you can see this in my pic.
Reassemble the programmer and reinstal it.
Match up the existing lines to your new programmer lines and all thats left is the glovebox and hush panel.
But I would test first in case you didn't get a line in good enough to seal up.
