1. INTRODUCTION
This instruction sheet covers the assembly procedure
for J1939 CAN network system.
IMPORTANT: DO NOT use incorrect terminal
combinations when assembling J1939 connections.
To avoid network system problems, DO NOT use
terminals other than specified. In addition, differing
male blade thicknesses causes a low normal force
and intermittent contact, which can result in failed
communications between network components. The
following assembly procedure must be used for this
network system in data bus communications.
Reasons for reissue of this instruction sheet are
provided in Section
5, REVISION SUMMARY.

3. ASSEMBLY PROCEDURE
Ensure that all contacts are crimped to the wires
according the appropriate Application Specification:
114-5091 (for receptacle contacts) and 114-20045 (for
tab contacts), then proceed with the following.
3.1. Intermediate Module Assembly
1. Insert the two contacts of the module plug into
Circuits 1A and 2A of the cap housing and the two
contacts of the continuing data link into Circuits 1B
and 2B of the cap housing. Refer to Figure 2.
2. Insert the secondary lock
into the front of the cap
housing until it is fully seated.
Ensure that the 4 blades
of the secondary lock are
mated to the 4 contacts at the back of the cap
housing.
3. Repeat Steps 2 through 3 to assembly each
intermediate module assembly.
