Look at the harness that goes to the cluster, you will have 3 green plugs, on the other end of that harness will be 2 large plugs.
Are they square, one black and one white(05-07)
or,
Rectangle, one brown, one white. (03-04)
The only rewiring is for outside air temp,
Need to put a resistor in for the diff temp so the light goes off and swap 2 wires so the abs light goes off when there isnt a fault and on when there is. Its just reversed...
