Hi all,

Getting ready to wire the fog lights that I recently installed on my 1965 Plus 4..

I'm installing these Lucas replicas from Moss Motors.

I was able to locate the red/yellow trace wire that runs from the dash toggle to the front of the car (it is currently disconnected from the dash). When looking at the factory wiring diagram, it appears the hot (red/yellow trace) wire from the toggle is simply split with a snap connector and then connected to the foglamps (which I plan to ground to the chassis.)

I plan to add a 10 amp inline fuse to the hot (red/yellow trace) wire before the snap connector...question is, do I need a relay as well?

Looks like the factory didn't even fuse the foglamps - is a 10 amp inline fuse sufficient protection?

I know that a relay is often recommended - but it seems that's the case for more modern, electrically demanding, Morgans.

Any advice is appreciated.
