Looking to wire the fog light as 4th brake light. Wanted to do a plug and play solution. I think I found the connector and a source. Not 100% positive these are the right ones but pretty sure they are. Ordered some and will update post later to confirm either way.
Sumitomo TS 090
A guy in Japan sells these. Bought some other connector from him for my Honda before.
