How hard would it be to plug in a bridge plug (so you don't have to cut into the harness) and hook up a switch in the console box to enable/disable skip shift?
Out of curiosity...why would you want to have the ability to turn it back on?
I must seriously be missing something. I have the manual transmission. When I rev high in first gear I get a message in the LED display that says something like (1-4 for better fuel economy) or something. It's just a message and only shows when I get the speed high enough in 1st. I'm not obligated to shift to 4th. What's the big deal? I just ignore it.
The skip-shift is supposed to prevent you from shifting into 2nd gear if you try to shift while the message is displayed.
