I have an old "H" style transmission and would like to be able to display "R" when in Reverse. I have wired the reverse lights so a signal can come to the dash (C187) but am at a loss as to how to let that signal change the display.
I thought about a new channel, 'Reverse Light' with conditions to change the Gear channel when voltage was applied, but that channel is generated and can't be used.
Anyone successful in doing this?
