1941 Cadillac Wiring Harness

John, I favor either Naragansett or Rhode Island wire, both (ironically) in Rhode Island. One word of advice: don't order your harness from a catalogue by year/make/model--send your old harness in and tell them to replicate it, and include any modifications you might want like turn signals, etc. Manufacturers made running changes to wiring harnesses thru out a particular model year, and you may not "have enough wires" with an off the shelf harness--it's happened to me.

I installed a complete harness from Rhode Island Wire in my '47 Packard with O/D and Electromatic clutch. It was a perfect match to the original and I did not have one problem with the installation. I am very satisfied.
