Q: Gauge Conversion for 1967-1968

I’m getting ready to convert from idiot lights to a gauge cluster on my 1968 conv. I’ve been to the FAQs and there’s a lot of good related stuff, but I do not see a wiring diagram for the gauges. Did I miss it?

A: Chip as you can see theres lots of discusion on gauge conversions. 1967 and 8 pose a big problem in that the pinout is different on the dash connector. However regardless of what you hear,its not as simple as changing a few pins around. Sure you can get the oil and water to read, but to get the ammeter to work you will have to rework the harnesses all the way to the voltage regulator. This will mean a new forward lamp harness as well as a dash harness. There are extra wires in the rally gauge setup that the idiot light ones dont have. You could redo the lamp harness and add wiring to the bulkhead connector , change the pinout and add wiring to the dash harness. OR buy the correct harness(s). Any way you go its not as easy as changing speedo /dash assembly. 69s are a different story… bout time they wised up.
