For my 1958 442, I made a completely new wiring harness using modern, vintages style, cloth covered wire from ‘ton.performance’ on e-bay. They offered several colors and gauges that allowed me to match what I found on the cat. I used asphalt covered wire loom from ‘ditch612’, also I purchased On eBay, for the wire bundling going through firewall and on the engine bay wiring to the generator, lights etc. To wrap up the cover junctions, I used Tess Coroplast cloth tape sold by ‘jennjro0’ (eBay). I drew up a wiring diagram to use - I need to update that with the ‘as-built’ before I post it. Ron
