H. Sequent / OEM Electrical Connections:
Proper Wire Splicing
Terminal Crimping Types:
There are two types of terminals used in the installation of the Sequent P&D wiring harness. To
ensure a good crimp, use the appropriate style crimping tool (including correct gauge) as illustrated
below.
NOTE:
Not all crimping tools are made exactly the same. Experiment with different tools to
achieve the best crimps possible before working on the vehicle’s wiring harness.
The first is the “U” style splice crimp used to splice the Sequent P&D harness circuits to the OEM
harness circuits.

The second is the “Barrel” style, non-insulated lug terminal used to connect the Sequent P&D
harness to the battery post terminals.
