Breakout Boxes and "V" Cables

Breakout Boxes and "V" Cables







Breakout Boxes are used to:
- Provide a convenient "tap" into an electrical circuit.
- Minimize the possibility of damage to control unit connections and wire harnesses during diagnosis of electrical/electronic systems.
- Ensure solid meter connections for proper diagnosis, this in turn will help the technician to be more organized and efficient.
- Provide easier access to circuits for testing with equipment such as, multimeter, DISplus tester or other diagnostic tools.


CAUTION: Breakout box cable connections are universal in order to fit the varying coded connectors found in the vehicles. Always confirm that you are connecting the correct control module into the system harness that is on the other side of the breakout box. System damage will occur if it is not the correct system.


Example: DME and EGS/AGS control modules both utilize an 88 or 134 pin control module. These control modules reside in the same E-Box on most vehicles. The control modules are coded to prevent unintentional cross connecting at the vehicle harness. But, this connector coding is not present on the 88 or 134 pin breakout box(s). Result: A DME control module could be connected to a transmission control system. Damage will result!

Several different types of breakout boxes are available depending on the particular system being diagnosed.

55 pin Breakout Box
P/N 81 12 9 425 091




Used with control modules that have single multipin plugs from 25 to 55 pins.

- L-jetronic
- ABS
- Motronic
- EGS

Adapter cables are required.

83 Pin Breakout Box (Red Face) P/N 90 88 6 614 420




When used with ABS/ASC 5 system, no adapter cables are required. See SIB 04 10 95 about an adapter harness for use with the Teves Mark IV G ABS system of the E36.

88 Pin Breakout Box (Green Face) P/N 88 88 6 614 410




Used with control units that have up to 88 pins

- DME
- EGS/AGS
- ZAE/MRS
- LCM

No adapter cables are required when connected to a DME or EGS/AGS control module. See SIB's 04 26 96 and 04 15 96 about adapter harnesses for ZAE/MRS and LCM systems.

134 Pin SKE Control Module
Breakout Box Set
P/N 90 88 6 121 300




The 134 pin modular connector DME and AGS control modules use a combination of breakout boxes for troubleshooting. The part number above provides three breakout boxes and five adapter harnesses. The two outside edge connectors use the familiar 26 pin breakout boxes. The three inside connectors use the boxes from the ordered set.

26 Pin Breakout Box
P/n 88 88 6 611 459




Used with system or peripheral control module that have up to 26 pins. This breakout box is used in conjunction with adapter cables called "V" Cables. There are many different types of "V" cables for the various connectors found on the vehicles.

60 Pin Breakout Box
P/N 90 88 6 614 390




Used for connecting all adapter leads with 27 pin to 60 pin plug connections.
