Wiring and Connectors

Wiring Harness Service

The control module harness electrically connects the
control module to the various solenoids, switches and
sensors in the vehicle engine compartment and
passenger compartment.
Replace wire harnesses with the proper part number
replacement.
Because of the low amperage and voltage levels utilized
in powertrain control systems, it is essential that all wiring
in environmentally exposed areas be repaired with crimp
and seal splice sleeves.
The following wire harness repair information is intended
as a general guideline only.  Refer to 

Chassis Electrical for

all wire harness repair procedures.

Connectors and Terminals

Use care when probing a connector and when replacing
terminals.  It is possible to short between opposite
terminals.  Damage to components could result.  Always
use jumper wires between connectors for circuit
checking.  NEVER probe through Weather-Pack seals.
Use an appropriate connector test adapter kit which
contains an assortment of flexible connectors used to
probe terminals during diagnosis.  Use an appropriate
fuse remover and test tool for removing a fuse and to
adapt the fuse holder to a meter for diagnosis.
Open circuits are often difficult to locate by sight because
oxidation or terminal misalignment are hidden by the
connectors.  Merely wiggling a connector on a sensor, or
in the wiring harness, may temporarily correct the open
circuit.  Intermittent problems may also be caused by
oxidized or loose connections.

RODEO 6VD1 3.2L ENGINE DRIVEABILITY AND EMISSIONS

Be certain of the type of connector/terminal before
making any connector or terminal repair.  Weather-Pack
and Com-Pack III terminals look similar, but are serviced
differently.

PCM Connectors and Terminals

Removal Procedure

1. Remove the connector terminal retainer.
2. Push the wire connected to the affected terminal

through the connector face so that the terminal is
exposed.

3. Service the terminal as necessary.

Installation Procedure

1. Bend the tab on the connector to allow the terminal to

be pulled into position within the connector.

2. Pull carefully on the wire to install the connector

terminal retainer.

Wire Harness Repair: Twisted

Shielded Cable

Removal Procedure

1. Remove the outer jacket.
2. Unwrap the aluminum/mylar tape.  Do not remove the

mylar.

047

3. Untwist the conductors.

4. Strip the insulation as necessary.

048

Installation Procedure

1. Splice the wires using splice clips and rosin core

solder.

2. Wrap each splice to insulate.
3. Wrap the splice with mylar and with the drain

(uninsulated) wire.
