1972 Gauge set-up

[dennis3d]

I currently have the 3 gauge setup bezel---wanting to go with the 7 gauge setup to keep from having to go after market gauges...got to buy new one anyway-- will the wiring harnesss plug from 3 work on 7 setup--then what do I need to do to get all the gauges working? Thanks for help

Nope and if you just plug it in and go you will surely fry your fuel gauge and possibly cause other havoc... there is a how-to on GMC Pauls site. I will see if I can find it.

Here is one...
