I think you would have to go under the hood with the wires first.
No kidding! I had about three tranquilizers before I got the wires fished through on my first one I like to go down where the factory harness goes but its really hard to get it to go behind the brace and around into the tunnel. This is hard to explain maybe by the weekend I will get some pics. Factory instructions on other electrical items show to go around that brace more into the front of the machine. But it tends to rub on things if you are not careful.There is no good route. There is a route, however.
Follow the shifter cable. Take some tranquilizers first.
Bane, do you just pull with pliers or is there a special tool. Worried about breaking the rivet with pliers.On my 13 900, I pulled the plastic rivets from the floor tunnel cover and removed it and it will give you wide open access to come from the front to the rear. Only takes about 5 minutes to remove it.
