The cathode end of glass-encased diodes is indicated by a stripe, a series of stripes, or a dot. The cathode and
anode ends of metal-encased diodes can be identified by the diode symbol marked on the body.

Some wiring is done with multi-conductor ribbon cables with differently colored conductors. The colors of these
cables follow the EIA color code, and the brown conductor should connect to pin 1 of the associated connector.
