Wiring Harness Question

[chevykevy]

I have a 1968 Short box with the plain guage cluster. It has only the fuel and speedometer guage. I would like to put in a set of guages with the four windows on the botttom which have the amp. meter, temperature, and oil pressure guages as well. Do I need to replace the wiring harness, Junction Box, or what? , to allow for the temperature, and ammeter to work? aAny help would be appreciated.,

The following link has instructions for doing the swap. Scroll about half way down and look for "Swapping A Idiot Light Dash Out To Gauge Dash".
