I checked the connection. Nothing loosened. And I even grinded (sandpaper) some areas to make sure having 100% connection (earth).
Seems to be I need to change complete wiring starting from bulb cylinder down to connector plug in (2 pins)?
Perhaps changing it would get it working again. You likely have the mid-year, early version of the TS hood harness that is not currently reproduced. The later version does fit and function but differs in appearance. Personally, I would try and search out the issue if I still had an original harness with the cloth/tar conduit on it. On my 11/2/66 built San Jose example, I did replace this many years ago (similar issue) with the later version and more recently built my own "early version" by sourcing a damaged original to use as a pattern, an Alloy Metal (current replacement) and some new cloth/tar conduit. I removed the incorrect bulb sockets, cut the wiring down for the correct lengths and re-assembled the correct bulb sockets onto the new wiring. Not perfect, but a very nice attempt in my opinion (given the lack of availability of a correct one). If my guess is correct, (using your build date), your hood wiring is threaded through two holes in the inner structure and at those holes (in the hood structure) you should have the grommets in the hood. You should also have 3-4 push-in clips holding the wiring to the hood. (later versions used "P"-shaped plastic hoops and bolted to the hood louver mounting studs, yours should not be this way)
