TRACTOR-TRAILER CONNECTORS
Heavy duty sockets, plugs and assemblies that withstand the rigors of trucking thousands of miles in dust and dirt, rain and
snow, heat and cold, yet maintain the all-important electrical continuity between tractor unit and trailer. With the increased need
for more circuits on the trailer comes the need for more poles in the connectors. The 13-pole connector contains added circuits,
yet is able to link up with standard 7-pole trailers when necessary. Green connectors clearly indicate dedicated ABS plugs and
sockets, yellow identifies a 13-pole connector. Tractor-trailer connectors are also employed in agricultural vehicles.
13-pole connectors
12301 Plug
Provides six additional tractor-trailer circuits within the dimensions of traditional 7-pole connectors. Adaptable to a wide
variety of wiring combinations, including multiplexed circuits.
Surpasses SAE J560b performance standards. Conforms to this
standard for interchangeability between 7-pole and 13-pole
connectors. Distinctive bright yellow identifies 13-pole connectors. Robust glass-filled plastic housings cannot rust or corrode.
Ground terminals accept up to 8AWG wire, 7 pole terminals up
to 10AWG, smaller 6 pole terminals up to 14AWG.
Plug locks into the socket, utilizing the spring-loaded socket
door. Spring-grip contacts have self-adjusting spring bands to
maintain long-term uniform electrical contact with socket pins.
O-ring at the plug end prevents water from reaching the
contacts. Strain relief and grommet seal isolates the contacts
from mechanical strain, and provides extra moisture protection.
Cable retainer maintains secure cable connection. Replaceable
interior. Includes six 31784 crimp-on connectors to mate
with the six smaller pole terminals. See Section Q6.
12300 Socket
Gasket-sealed socket door is
spring-loaded and locks onto
the plug. Solid brass contact
pins. Rain hood extends beyond
the pins to protect the interior.
The 5º downward pitch drain
channel inside the socket reduces
water retention. Three mounting holes on the flange:
.33" (8.4mm) diameter, 2.93" (74.6mm) on centers.
Includes six 31784 crimp-on connectors to mate with
the six smaller pole terminals. See Section Q6

recommendations, and are compatible with other standard
(J560b) connectors.
Sockets
Ground terminal accepts wires up to 8AWG, other terminals
up to 10AWG. Solid brass contacts are aligned to assure
proper contact and minimal voltage drop. Wiring codes are
embossed on the insulator. The door is spring-loaded and
fits over a mating ridge on the socket face to minimize
penetration of dirt and moisture. Housings are constructed
from corrosion-resistant diecast metal or rugged glass-filled
plastic. Contacts are either self-grounding or insulated.
See Section Q3 for socket interiors.
Color-fast green glass-filled plastic insures quick identification.
Spring-loaded door is marked 'Trailer ABS' to further lessen any
chance of misconnection. Mounting holes on the flanges are

With Spring Grip Electrical Contacts
Same as 12075, but with split-pin contacts.
Cole Hersee spring grip contacts contain a self-adjusting spring
band that maintains contact pressure from socket to pin.
Greater contact pressure not only gives greater electrical
efficiency, but also makes coupling and uncoupling uniform,
and minimizes buildup of dirt. In competitive plugs, conventional contacts tend to widen after repeated use: the Cole
Hersee plug has individually sprung sockets to insure
maximum contact year after year.

Diecast metal housing. Replaceable interior. Wiring codes are
identified on the insulator. Cable clamp holds all wires securely.

INFORMATION
Wiring colors
AWG conversion
Colors are not universal, so it's wise to check proprietary
instructions, and to make an electrical test.
American Wire Gauge (AWG) is a US standard set of nonferrous wire conductor sizes. Non-ferrous’ usually implies
copper, but it includes aluminum and other metals and alloys.
The following colors are very commonly used.
The "gauge" refers to the diameter. Typical household wiring is
AWG number 12 or 14. Telephone wire is much thinner at 22,
24, or 26. The higher the gauge number, the smaller the diameter and the thinner the wire and the less current it will safely
carry. Thicker wire carries more current because it has less
electrical resistance over a given length. Thus larger wire is
used with high currents and when the voltage drop along its
length must be minimized. For example: High output alternator
wiring might be 2 AWG and the starter cable for a mid-sized
engine 1 or 0 AWG.

Yellow - Left turn and brake lights
Brown - Taillights and clearance lights

Red - Backup lights
The metric equivalent is simply the diameter expressed in
millimeters, and thus can be easily measured with calipers.

Electronic unit permits a towing vehicle with two lighting
circuits for each side to operate lights on a trailer with a
single circuit each side. Eliminates the need to rewire the
trailer or to add additional lights. US laws require stoplights,
turn signals and tail lights on trailers. See Section K4.

Inline trailer connectors
Best practice
for assembly of plugs and sockets
12400, 12401, 12500, 12501
Not supplied with wire, but the terminals are identified
by numbers.
Properly installed tractor-trailer connectors are critical to the safe
performance of a rig, which are routinely subjected to vibration,
extreme weather conditions, as well as mechanical forces.
We highly recommend that a trained technician performs the
installation. It is the responsibility of the end-user to take into
account the mounting location and environment, conductor type,
size, flexibility and other installation parameters.
7-pole connectors
Accept wire up to 14AWG

7. Rear, clearance and side marker lights
Review the assembly procedure before assembly. A common
error is to not slide a clamp, boot or housing onto the cable
before connecting the wires. Recommended tools: screwdriver
(preferably with torque limiter); soldering iron (preferably a
solder pot), solder and flux; wire stripper and cutter; and ruler.
Cut the cable, and strip the jacket to the recommended length.
12-pole connectors
Strip the wires to the recommended length, and tin them.
Maintain a tight strand bundle before tinning, so that there are
no loose strands. Re-tin if necessary. This makes it easier to
insert the wires into the terminal, and helps to properly position
the tinned strands at the right depth.
Pins 1-7 accept wire up to 14AWG, pins 8-12 up to 8AWG.

Slide the housing, spring coil or boot over the cable.
Properly insert and position the tinned conductor into each
terminal. Locate the tinned portion under the terminal screw
before tightening the screw. Tighten the termination screws to
the appropriate torques.
Inspect the terminated connection for cut or loose strands,
fragments of wire insulation between the terminal/conductor
connection, bent terminals, loose or stripped terminal screws
and other visible problems.
13-pole connectors
Check that the correct connections have been made, by re-checking that the conductor jacket color matches the insulator coding.
Pins 1-7 accept wire up to 14AWG, pins 8-13 up to 8AWG.
Pins 1-7 as for 7-pole connector, pins 8-13 auxiliary.
Carefully slide the insulator into the connector housing, making
sure that the insulator is fully seated. Don’t twist or lever the
terminated conductor after it has been inserted and locked into
the insulator. This may damage the terminal and put stress on
the terminated connection.
Finally tighten the housing screw or cable clamp.
In order to keep a plug clean when not inserted in a socket,
we recommend the use of the 11750 Stor-A-Way Plug Holder –
see Section Q6.
