The switch actually makes contact on the negative side of things. So, just 
find the wire in the harness from the existing automatic multi-function 
switch, it's Brown/Black. It goes to the TCU. Cut and run it to the existing 
manual trans switch. On the other side of the switch, connect a wire there 
and to ground.
