Wiring Harness Under Dash Identification

[Geoff McCord]

I'm hoping for some help identifying the model application of an under dash wiring harness. Are the B and C harness' the same? If not, is there a way to tell the difference. I don't have color wiring charts so it is hard for me to tell. It appears the headlight switch, which is attached, is a B/C switch, but that may not be original.
Thanks in advance for any shared knowledge on this.

those are very good. Was their one for a 1957 T1 Coupe as well ??

HUGO, that's exactly what I was looking for. I guess a period reread of past issues would do a lot to keep these things fest in ones memory.
Many thangs for pointing me to a right place.
