bartamos,
I cannot confirm that those items worked prior. I bought the truck with a motor needing attention and I swapped it out for 261. all engine related wires were hooked up prior to the battery, except the last item horn installation. when I was retrieving those wires that were tucked in by the inner fender, I suppose one of them could have touched the inner fender instead of each other.
Looking at the extreme quality build of this restoration I was assuming everything was correct. Every wire, every terminal, every component looks like brand new. Yes I know what it means to assume. Most of if not all wires have number labeling on them so I’m guessing they used a chart and or knew what they were doing.
Going forward, I will try to verify all connections, wire routing on components etc.
