Well it's been awhile but I am started on the rewire of my 49. Things are going pretty well. Taking my time reading instructions, hooking things up and rereading . Just to make sure it's right. I'm going towards headlights and when taking out old wiring there is a relay, I think, AR-501 12 volt 2x 15 amp where the wires went to then to headlights and fog lights. Fog lights were on their own separate switch. There was also an extra 10 Amp fuse wired into the relay and lights. Is this something I need to reincorporate into system?
