I did the reverse implement option (RIO) bypass the other day. Many have done it and it's very simple. In all about a two minute step. The longest part of preparation was making the wire jumper.
I used a piece of 14 gauge wire with male spades crimped at each end.
I then disconnected the wire harness from the bottom of the RIO switch found on the left side of the dash. Open the hood and just pull the harness plug away from the switch.
Then I just slip the spade ends of my jumper wire into the female end of the wire harness that is removed from the base of the switch.
Once I completed that I just pushed/placed the harness assembly back under the dash area and zip tied it off to something to keep it from moving around necessarily. Gave it a test and the mower conituned to run when going in reverse, no warning light thrown. Easy to convert back in a pinch if you were dropping your tractor off for warranty work. Not that it would necessarily matter anyway.
