I have put a 5A fuse in the PC8. Seems ok.
I forgot to mention that I do have an in line fuse with my lights' wiring with sumitomo connectors up front. I used to Eastern Beaver kit for the front plug (purchased with the PC-8).
The only reason I did not have the fog light switch is that rugged roads never processed my order and never responded to emails asking about it. I just figured screw it, I don't really need the switch since they'll be on all the time.
