47 - 55 Chevy Pickup Classic Update Wiring Harness

The Classic Update Series is a complete wiring system in a box!

That means it includes everything you need to modernize your classic vehicle: Headlight, Dimmer, and Ignition switches; Boots, Tubes, and Grommets; Fuses, Relays, and Flashers; Original Connectors, Terminals, and Disconnects.

NOTE: These kits are recommended for MODIFIED original vehicles, not OEM restoration projects.

Kit Includes:

Accessory disconnect provided for connections to power windows, power seats, cruise control, fuel pump, power door locks, extra radio (CB), or optional power accessory.

New floor dimmer switch is provided. Wire length and connection accommodate original floor mount dimmer switch.

Standard turn signal flasher, hazard flasher, and horn relay mounted on fuse panel.

18 Circuit Fuse box and custom mounting plate are designed for bolt-in under dash installation. All required hardware supplied. Location selected for easy accessibility and clearance of under dash accessories such as all gauge packages, wiper systems, heating and air conditioning systems, and stock original or aftermarket GM tilt steering columns.

Steering column connectors will plug directly into most aftermarket steering columns as well as 1969 and later GM columns which utilize stock GM turn signal switches. The original column can also be wired by using the supplied mating connector and terminals.

Instrument Cluster wiring is designed with a "cluster harness disconnect" system for easy service and assembly. All original terminals, connectors, and light sockets are also supplied for original cluster gauges. However, the best aspect to the disconnect system is that any gauge cluster package can be easily and neatly wired in.

Heater control panel lighting, power, and blower motor leads are included for original style heaters as well as aftermarket heat and AC updates such as HOTROD AIR, VINTAGE AIR, etc. Connections are also wired in for the glove box and cigarette lighter.

Replacement headlight switch with internal circuit breaker included. Retention collar nut, adjustable length shaft, and custom knob are also included. Extra connectors and instructions are supplied for installation of original headlight switches.

Front lighting includes extra long leads for special routing when custom under hood appearance is desired. All headlight, park light, and directional light connectors and terminals are provided, as well as a switched trigger wire for electric fan relay (usually recommended with AC).

Rear body harness assembly is designed to plug into the main harness in the original position utilizing existing retainers. Flexibility in harness design allows for original or custom routing. Both pickup and suburban models are accommodated. Rear body wiring includes backup light wires and mating connectors for backup light leads. License plate lead, connectors, and terminals included. Fuel tank sender wire and terminal included. Leads and terminals included for jamb switches and dome light.

Engine wiring includes connectors for points type and H.E.I. distributors. Power and tach connectors supplied for GM H.E.I. distributors. Alternator connectors are supplied for GM "SI" series internal regulated and all "one wire"alternators. GM "CS" series alternator connector available separately.

Engine wiring includes starter and gauge sender leads for water temp, oil pressure, voltmeter, and tach. Heavy 8 gauge alternator leads are supplied. Power circuits are fusible link protected.

New ignition switch is included. Additional connectors and instructions are provided to use the original ignition switch or column mounted ignition switch..

Color schematics and easy to understand installation instructions included.

Please note: Classic Update Kits do not support Ampmeters

Note: This wiring is designed to work on Internally regulated alternator and have a 12v feed for the coil/distributor/ignition box. This kit IS NOT set up with a resistance wire for a standard, points type ignition system. It is wired with a full 12 volt primary ignition feed that is hot in both the start and run positions. It will support HEI, MSD, other electronic ignition systems, as well as computerized Fuel Injec- tion systems. If you wish to run a points type system, there are illustrations on the engine connection pages to do so. Extra parts that are not included in this kit will be required to complete that operation. (see our other items).
The early GM/FORD generators and externally regulated alternators are just not up to the task of providing power to an expanded wiring system like these classic update kits. The point of this kind of kit is really to allow people a way to upgrade and expand their wiring system and so an alternator upgrade is usually part and parcel to this kind of upgrade.
