NOTE:
Take great care not to get the cables to be joined dirty as this will adversely affect the continuity of the electrical conduction. While heating the thermal shrinking tubs, as a result of the high temperatures reached, the drier and the heat shield must not, under any circumstances, come into contact with cladding parts or other components.
Fit the thermal shrinking connection tubes (1) onto the two sets of harness wires and use an air heater (2a) with heat shield (2b) to heat the thermal shrinking tube (2c) until the ring of solder melts; then wait for it to cool.
NOTE:
The air heater (drier) used in this procedure is commercially available.

NOTE:
Apply insulating tape to the two wires individually and then combine the wires with the main wiring and tape to create a more compact bundle.

Remove the nut on the ground pin near the central pillar and open the vehicle wiring retainers along the side panel.
Insert the T-box ground lead into the wiring retainers (1a) and close them, then position the T-box harness ground ring (1b) on the ground pin over any existent wiring and tighten securely.
NOTE:
If there are previously removed wires connected to this ground pin, be careful to insert the ground wire of the T-box harness so that it is offset by 90° with respect to the previous ones.
