here's an excerpt from the PDF:
2.2.8 Manual Shift Connection (Optional) – C8
The TCU is configured such that it's possible to have fully manual upshifts and downshifts at the flick of a
switch like a bump stick. This works by first activating the manual mode with one switch to Terminal C.
Once activated, the transmission can be bumped up (Terminal B) or down (Terminal C) through the
forward gears via an On-Off-On momentary rocker switch.
The default connections are to be made as follows:
• Terminal A (red wire) - momentary +12 volts for bump down
• Terminal B (yellow wire) - momentary +12 volts for bump up
• Terminal C (blue wire) - +12 volts to activate manual mode
Note: These can be changed to momentary grounds within the software.
Caution: Be aware that serious engine damage could occur due to over-revving if downshifts are made at
too high of vehicle speed. The TCU cannot override your input while in the manual mode.
