vehicle interfaces do not have their current load capabilities exceeded, and that the respective control devices are not overloaded. Added
wire size should be at least as large as the wire to which it is attaching in order to maintain fuse protection.
A Packard electric wiring repair kit is available through Kent-Moore (GM P/N 12085264, Kent-Moore P/N J38125-4). This kit contains
instructions, tools and components for making repairs to wiring harness components. This kit would also greatly assist in accomplishing
necessary add-on wiring, such as body marker lamps, so that system reliability/durability is maintained.
Electrical wiring components can be obtained through your authorized GM dealer. Many Packard Electric components are also available
through Pioneer Standard Company (1-800-PACKARD). Pioneer may also be able to assist in making necessary wiring additions by
providing custom wiring stubs or jumpers to your specifications.
Fusible Link Repair Procedure:
1 . Cut damaged fusible link from wiring harness assembly splice.
2. Strip insulation from harness wire as required to splice on new fusible link.
3. Fabricate a new fusible link wire approximately 6 to 8 in. long from the same wire size as the original link. (Acceptable fusible link
material will be imprinted with the wire size and the wording to identify it as fusible link. Fusible link cable is not the same as normal
vehicle wiring.)
4. Terminate fusible link harness wire with a suitable compression splice clip, and solder with an electrical grade rosin core solder.
Wrap splice area with tape to provide electrical insulation, as well as mechanical strain relief at the splice.
5. Strip, terminate, solder, and insulate remaining end of fusible link with appropriate termination to be compatible with the rest of the
electrical system.
6. For further information, refer to the instruction manual in the wiring repair kit referenced elsewhere in this section.
Accessory Power Supply Feeds
For power requirements to service additional devices to be added by body builder/upfitter, the power supply source must be from the studs
on the underhood electrical center mounted on the left hand shear wall in the engine compartment.
A junction block has been provided behind the driver’s side ‘B’ pillar. Both switched and unswitched power junction terminals are
available (See Owner’s Manual for compatibility). All additional loads should utilize these terminals.
NOTE: A ground stud has also been provided above the junction block.
