Cards representing a connector are punched, sorted, and then used to printout wiring documentation for that connector. When wiring changes are made, new cards are punched and the wiring documentation is reprinted to reflect the latest configuration

NASA TECH BRIEF 
NASA Tech Briefs announce new technology derived from the U.S. space program. They are issued to encourage commercial 
application. Tech-Briefs are available on a subscription basis from the Clearinghouse for Federal Scientific and Technical 
Information, Springfield, Virginia 22151. Requests for individual copies or questions relating to the Tech Brief program may

Wiring Harnesses Documented by Punched-Card Technique 
A technique has been devised for documenting wire 
harness details by use of punched cards in conjunction 
with a card sorter and a card printer. This documenta-
tion technique was devised to save the drafting time 
and expense customarily required to prepare pictorial 
drawings representing harness details (connector pins, 
wiring destination, wire size and function, and any 
pertinent twist or shield information). Any wiring 
changes that are made can be rapidly documented with 
this technique, saving the time and cost which would 
be required to correct and reissue drawings. 
In the punched-card technique, all cards represent-
ing a connector are punched, sorted, and then used to 
printout wiring documentation for that connector. 
If wiring changes are made, all cards involved in the 
change are separated from the other cards, new cards 
are punched, and the wiring documentation is re-
printed to refle& the latest configuration. 
After the cards are punched and sorted according 
to harness, they are then sorted according to connec-
tors or splices within each harness. Each of the con-
nector stacks is next arranged in consecutive order 
according to pin. When the cards are arranged by 
harness and connector and are in consecutive pin 
order, they are run through a card printer to obtain 
wiring harness documentation. The printing format is
basically the same ai the typical 80-column ca'rd for-
mat, except that 120 spaces are available on the print-
ing format. 
An entire harness printout consists of a printed sheet 
for each connector and for each splice in the harness. 
The card file can be used to printout wiring harness 
information in response to specific requests.
