I have a 63 series 62 convertible.
Thought it would be a good idea to make the fin lights flash as well as tail/stop lights.
They did this in 64 i believe.
i replaced single filiment bulb holder in fin lamp, to a twin filiment.
ran a wire from the tail/stop lights to this extra filiment in the fin light.
its the pink wire on the color diagram i have. purple on passenger side.
Any how, yes it works and looks great, during the day.
problem is with side and full lights on at night....no flashing.
i can only think it must be the flasher unit cant cope with powering the extra filliment ive added to the top fin light.
Perhaps i need a 64 flasher unit. wiring on the 64 diagram looks just as ive done it.
Any one tried the same trick?
