New decal for the instrument cluster. How to?

Taking the cluster out is pretty easy,take the screws out,remove column cover and lower column,reach in the back and start unplugging the plugs,red and black wire and push the tab on the speedo cable at the gauge and it should pop out and repeat to install. The plugs can't be switched but the red/black wires can be but the board is marked red/black or just bolt them together and wrap them up real good and add an aftermarket volt meter.
