I went out and lifted the dash. On my 08 America there is a group wires that come from under the tank and were under the dash.
Plug 1 is red/blue & purple & brown wires.
Plug 2 is Red & Red/Green wires.
The above 2 plugs go to my tach.
There is a 3rd plug gray & orange wires. which I believe would go to a clock but I am not sure.
