Well, I just realized that Classic Parts did not include a key switch lamp socket in their replacement wiring harness. Wonder why? At first, I thought I simply forgot about it and looked for 20 minutes or more under the dash to no avail. So, I pulled my original harness out from storage and found it had six lamp sockets. Classic Parts harness only has five.
I suppose I could splice one of the original sockets into the one of the lighting wires, but wonder why Classic Parts left this off?!?!?!?!
