he's screwing you.
you don't have to remove the hood.
it takes about 15$ of wire and connectors.
might take you an hour if you can't walk and have to crawl around and drag yourself with your hands, and have to crimp the connectors with your teeth or something.
I typically can rewire an old for, especially one with no lamps in maybee 10 minutes if i'm distracted. less if in a hurry.
handfull of connectors.. some blck tape and or wire loom ( or both ) and the crimp / cut tool.
wire it point to point..then add tape and split or spiral looming
hard to find an EASIER tractor to rewire than a old ford. just ain't too many wires.
