I am in the process of rewiring my 68 xr7 with a Ron Francis 24/7 and was wondering about the dash panel. Correct me if I am wrong, but it looks like the temp gauge and the fuel gauge are wired through the little voltage regulator in back of the dash panel. Will that still be needed or can I wire directly to the gauges. I am using the original gauges except the ampmeter has been converted to volt meter and the tach has been upgraded too. Both done by Rocketman.
