In my zeal to deconstruct the 'B' so I could get going on stuffing the 302 in it, I neglected to mark the terminals on the backs of the switches when I removed the wiring and dash. Two years after the fact, I'm now installing the new wiring and, while I have the Bentley's diagram of where everything goes, I need some help on which terminal goes to where for the wiper, heater, and headlight switches. If someone out there could either give me which original color wire goes to which terminal or can give me "high speed goes to terminal 1", etc. I would be very appreciative. Switches are all out of a '78 model. Thanks in advance.
Try the wiring schematic from Advance Auto Wire website - you're model is listed on sheet 25

Doh! Went to the Advance site and just realized that the terminal numbers are indicated on the Bentley diagram I have. Thanks.
