A few 2-Step questions

My trans brake and 2-Step share a momentary switch button on my steering wheel. So as I release the TB button, the 2-step shuts off as well.

Both the TB and 2S have their own individual power buttons, so I can switch them on/off. I need the TB button for reverse, so I had to wire it this way. I don't want the 2-step activated when I go to backup.

As OP mentioned, I would install an on/off switch within the circuit specifically for the 2-step. You'll just have to remember to hit the switch before hitting the brakes.
