I am putting an EZ-Wiring kit in my 67. Trying to find out the wiring code for the Heater Switch, box, and motor. I want to use the original pigtails, but don't know what each wire is. Does anyone have a diagram of this or know what the wires are. No A/C. There is an orange wire runing to the motor on the firewall. I know this can't be too complicated. Any help? Thanks.
