Trailer connectors in North America

Trailer connectors in North America
A number of standards prevail in North America, or parts of it, for trailer connectors, the electrical connectors between vehicles and the trailers they tow that provide a mean of control for the trailers .

insertion [edit ]

In union american english, but most normally the USA market, it is very common for brake lights and become signals to be combined. On cars and abstemious trucks ( listed below american samoa Light Vehicles ) there is no formal standard, rather there is an accept standard. however, you can not be entirely surely until you have measured the current connection on the vehicle and dawdler that they fit each other. heavy Vehicles are standardized through SAE J560 which is alike to ISO 1185.

note that different color gull can be used for certain functions, which means that you can not trust the colors mentioned here without measuring the contact and wiring from case to font. In some cases – as in the flat 4-pin or 5-pin connection – it is fairly obvious which color that is connected to which pin. In case you have a vehicle that separates the left field and right side position lights into 58L and 58R – like many german cars – it is advisable to choose 58L to feed the taillights. These two circuits shall not be merged because it can create problems in the tow vehicle. If you want to be more advanced you can make a childlike association with two diodes that provide balance load of the circuits. note that the diodes have to be able to handle senior high school currents or that they are used to control a relay which in turn feeds the trailer. If you have a dawdler with a bunch of lights the diode and relay wire is preferred, but if you have a preview with a simple light arrangement it is normally sufficient to wire to 58L. Circuit that merges the left and right side position light circuits into a common circuit for position lights In market there are many especial converters [ 1 ] [ 2 ] [ 3 ] that solves the problem of connecting a cable car with european cable to a trailer with north american wire. What most of these converters do is to bring together the turn signals and stop lamp signal from a three-wire solution using 54, L and R into a two-wire solution using L54 and R54 according to DIN where brake faint and turn index uses the same wire and bulb for each side. These converters normally do n’t handle the case of separate position unaccented circuits for left field and correctly side in the tow vehicle .

Heavy duty vehicles – SAE J560 [edit ]

Trailer connectors in North America 7-pin trailer connection according to ISO 1185/SAE J560 ( Towing vehicle side ) physical design according to standard ISO 1185 [ 4 ] / SAE J560. [ 5 ] [ 6 ] The punch for SAE J560 is physically identical to the connection ISO 1185. The difference is that J560 indicates that the electric potential must be 12V and that wire areas shall be larger due to the higher currents needed when using 12V compared to 24V. Some of the pins in the connection have besides a slenderly different function. The functional differences are small, but the difference in voltage and current requirements makes the SAE J560 and ISO 1185 incompatible without the use of extra equipment in the form of electric potential converters. It is besides necessary to pay particular care to pin 7. note that the SAE J560 connection is not controlling the brakes. SAE J560 is typically used on heavy duty trucks and trailers with pneumatic brakes where alone the might to the ABS unit of measurement and indication of braking by brake light signal is required. The brake themselves are controlled using air pressure. SAE J560 was introduced in 1951, which means that older dense duty vehicles ( vintage ) may have other connectors .
The take after supplementary data exists for the connection :

  1. ^[7] Area for pin 7 shall be at least 10 AWG according to DOT till 10 AWG .

light vehicles, common connection types [edit ]

abstemious vehicles use a overplus of contacts, [ 8 ] [ 9 ] [ 10 ] but among these are two that are most common :

  • 4-pin flat connector, often used for simpler trailers.
  • 7-pin round blade connector, often used in caravans/RVs etc.

due to this there are unite vehicle outlets on the market that combine these two into a single module .

7-pin round blade connection ( SAE J2863 ) [edit ]

Trailer connectors in North America 7-pin blade connection ( Towing fomite side ) This is common for RVs and early bombastic trailers which have extra loads beyond the basic for dock lights and brake/turn signals. The standard is defined by SAE J2863, Automotive Trailer Tow Connector.

6-pin round connection [edit ]

Trailer connectors in North America 6-pin round connection ( Towing vehicle side ) This reach occurs on medium duty trailers that have both turn back lights and electric brakes .

flat 5-pin connection [edit ]

Trailer connectors in North America flat 5-pin connection ( Towing fomite side ) This contact is not as common, but is compatible with the 4-pin connection in the means that a tow fomite with this connection can be connected to a preview with the 4-pin flat fireplug. The supernumerary connection is much used to block the billow brakes when reversing with the trailer .

flatcar 4-pin connection [edit ]

Trailer connectors in North America flat 4-pin connection ( Towing vehicle side ) This contact is one of the most frequent contacts on the trucks in North America. It contains the minimum necessary signals for complying with regulative requirements in the United States .

Less coarse connectors [edit ]

These contacts are less common, and the electrify of these may differ from what is listed hera, a well as Application area. The contacts can be for example be used for task light, etc .

SAE J560-like, type 1 [edit ]

Trailer connectors in North America 7-pin SAE J560-like, type 1 ( Towing fomite side ) Although this has forcible similarities to SAE J560, it is not electrically compatible and should be avoided. Wiring should be made in accord with SAE J560 alternatively to avoid problems .

SAE J560-like, type 2 [edit ]

Trailer connectors in North America 7-pin SAE J560-like, type 2 ( Towing vehicle side ) Although this has physical similarities to SAE J560 is not electrically compatible, and shall be avoided. Wiring shall be in accord with SAE J560 rather to avoid problems .

6-pin rectangular connection [edit ]

Trailer connectors in North America 6-pin orthogonal connection ( Towing fomite side ) Because this connection has pins in two rows, it is not backwards compatible with the 4-pin and 5-pin flat connectors .

5-pin circle connection [edit ]

Trailer connectors in North America 5-pin round connection ( Towing vehicle side ) This liaison is less common, and may have wholly different wiring than that shown hera. The wiring is same as for the 6-pin polish connection with focus on pin ( Reversing lamps ) excluded.

4-pin orotund connection [edit ]

Trailer connectors in North America 4-pin round connection ( Towing vehicle side ) This connection is available in some cases rather of the flat 4-pin connection. It is less common on the U.S.-built vehicles, than 4-pin two-dimensional connection, but is still used in the older truck and SUV setups. A classifiable sport of the trailers that require this character of connection is the fact that they do not have their own brake arrangement and stop along with the towing fomite. [ 11 ]

3-pin rung connection – DIN9680 [edit ]

Introduced by John Deere for agricultural hardware, [ 12 ] then used for other purposes, like yachts and general electric cables .
