J1939 Splice Pack Installation

Disassemble the Splice Pack

• To remove the cap, the installer must release the two locking tabs at opposite corners of the splice pack assembly.
• This is most easily done by inserting a small flathead screwdriver into the tabs, down along the side of the splice pack body and gently prying the cap up 1-2 millimeters.
• Once one side of the cap has been lifted, repeat on the opposite corner.

  Remove the TPA

• The TPA pulls out of the cable insertion side of the splice
• The TPA has three locking The large tab can typically be pressed down with a small flathead screwdriver. The TPA can typically then be removed from the other tabs and released. If this is not possible, depress the two smaller tabs as well and pull the TPA out of the connector body.
  

  Insert the Connectors

• The Zonar splice pack adapter can now be inserted into the back side of the Splice Saver connector body. Make sure the contact is correctly oriented so the contact locks into place. The cutout in the contact should face the center spine of the splice pack.
  

  Selecting the Right Connection Rows

• Match wire colors along the proper side of the connector (yellow to the yellow row, green to the green row). Make sure that the two J1939 wires are installed directly across from each other, as with slots B and H in the below example.
  

Reassemble the Splice Pack

Check the contacts are locked in place. Install the TPA into the bottom side of the connector body. This should easily snap into place and locks the contacts into the connector body. Reinstall the cap by pressing it into the open top of the connector body. Make sure that the cap is properly oriented (it may have a polarizing notch).   There will be other wires coming out of the back of the splice pack.
