You could have another dud switch, I'd be eliminating the switch completely before you go hacking at the wiring. Does the switch have 2 separate positions (2 clicks from the micro switch) if you pull it s-l-o-w-l-y forward you can hear 2 individual clicks. One click is flash and the second is dip. Im pretty sure that will be the problem, & only trying to give advice & up to you if you take it. These cars DEFINATELY had 4 single bulbs from original. Ive been out watching country music &had a dozen Bourbons, so hope this makes sense.

cheers
