The data link connector (DLC) is the multi-pin diagnostic connection port for automobiles, trucks, and motorcycles used to interface a scan tool with the control modules of a given vehicle and access on-board diagnostics and live data streams. [1] Prior to 1996, many OBD-I data link connector's were in the engine compartment, usually near the ...
The J1587 protocol uses different diagnostic connectors. Up to 1995, individual OEMs used their own connectors. From 1996 to 2001, the 6-pin Deutsch-connector was standard. Beginning in 2001, most OEMs converted to the 9-pin Deutsch. Some OEMs still use the 6-pin Deutsch. It has mostly been used for US made vehicles, and also by Volvo.
General Motors implemented both a 5-pin connector and a 12-pin connector, with the 12 pin connector (Packard/Delco/Delphi part number 12020043) being used in the vast majority of GM cars. Lotus implemented a 10-pin connector. The pins are given letter designations in the following layouts (as seen from the front of the vehicle connector):

The power connector on the 3½-inch floppy drive, informally known as "the Berg connector", is 2.50 mm pitch (distance from center to center of pins). The power cable from the ATX power supply consists of 20 AWG wire to a 4-pin female connector. [ 1 ]
The de facto standard for 3.5 inch drives uses a 34-pin header mating to an IDC Berg connector, collectively slightly smaller than the PCB edge pin connector and mating socket used for the 5¼ inch standard but with the same 34 pin definitions as the 5¼ inch standard. [7] A separate connector is provided for DC power. [1]
The many types are partly to prevent incorrect connection. [2] The larger connector sizes are the most varied, with designated connectors ranging from analog and digital signals to AC and DC power. [4] Each "coding" has a different keyway that prevents incorrect connection between incompatibly keyed connectors. [5]
The use of any other XLR-style connector is prohibited. The three-pin XLR connector is commonly used for DMX512, on lighting and related control equipment, particularly at the budget/DJ end of the market. However, using three-pin XLR connectors for DMX512 is specifically prohibited by section 7.1.2 of the DMX512 standard.
