is it the 'factory' one,
like this? no screw connections ... repro factory style harness?
the wiring diagram indicates red and pink on the ign sw, gray on the light sw for dashlights, the fuse panel isn't shown on it because it wasn't factory installed unless there was electric options ordered, at least in the earlier years ... power would usually come from the ign sw so that things were turned off when the switch was off ... not sure that helps much!
