The wires may not match color for color so you would have to match the functions. Start with the ones that are obvious. The white on both are ground wires. Make that connection. Blue on both are same function. Make that connection. All you have left is the red and black wire from the controller. The red wire is going to connect to the Lt green wire under the dash. The black wire is going to connect to the red wire under the dash.
