Hi James,

After Richard's nice quick search about the GMC harness from me
a completion of that. Stock number: 3500-5278504 and Part no:
GM-5278504 let us know: Harness, wiring, dash, assembly (CCKW)
(used with rotary type light Switch).
GMC parts list ORD 9 (15 July 1945) SNL G-508, showed us eight
diffirent dash wirings.
