'68 Dash Gauge(s) Wiring - Conversion from lamps?
I bought this '68 el Camino SS 396 back in July, it has the dash gauges in it, the Alt/Gen gauge did not work and the temp gauge registered some change when the engine warmed up but could tell it was not correct (might be the engine temp sensor?).
Make a long story short, I needed to replace the dash bezel since a previous owner cut the back of the radio mounting area out, got a real nice one, media blasted it, dyed and detailed it, so from that perspective ready to go. Pulled the entire dash out as well as the motor compartment wiring apart (do it on all the cars I get to make sure everything is wired correctly and no crappy splices, etc.....which I have found several already in this '68 and corrected!).
Now here is where I need some help....
The '68 el Camino apparently was originally non-gauge's from the factory, a previous owner added the gauges/tach (BTW, tach worked, just not wired very well, corrected that). In the gauge pod, the fuel is fine, the oil pressure is now manual, so those 2 gauges I don't have to worry about. The wiring for the Alt/Gen is not correct and I need some better reference for the temp gauge to make sure it is wired correctly. I have the '68 Chevelle/el Camino Assembly Manual and only wiring diagrams I can find (pages 12-D1 thru 12-D5) only make reference to dash wiring for the lamps (idiot lights), nothing for the gauges?
Need some help to find correct dash/motor compartment wiring diagrams for U14 RPO optional gauges?
