Are you aware the factory included the back half of the console wire harnes
in every 73. It can be found under the carpet between the seats. just plug a stock
console wireing harness in. You will have to run your own wireing for your CHT. As
to putting the gauges in the dash. I think that would look fubard . My 2 cents.
also you will need a Taco plate and the correct sender for your temp gauge.
There are 3 gauge under dash panels sold every where. If you use stock size
gauges that may be a problem finding a panel to fit. Dave
