This harness will replace the old and brittle 30+ year old wiring found in these cars.

18 circuits give you everything you need, plus more, for connecting standard factory components as well as components from the abundant aftermarket that has grown with the popularity of these cars.

This harness follows all of the same routing found on the factory harness which allows you to utilize the factory harness attachment points.

Each harness has a large 6 gauge charge wire to help accommodate those with upgraded charging systems, like those doing late model EFI swaps which have large 125+ amp alternators.

The harness/alternator is isolated from the battery through a 150 amp MIDI fuse (fuse holder, fuse and mounting hardware included). This means no fusible link to trace and re-splice if there is ever a major short in the system.

A fully integrated ground circuit ties all of the grounds in the harness together and directly to the battery to help do away with the “pain” of tracing a faulty ground connection. Grounds are also present on the core support, behind the gauge cluster and the tail harness; in the same locations the factory grounds were located.

All exterior lights (turn signals, marker lights, headlights etc.) have the correct sockets and bulbs pre-installed. You simply insert the socket into the lens, turn a ¼ turn and done.

Connectors for components such as the headlight switch, wiper switch, ignition switch, dimmer switch, wiper motor, among others, have the connectors and terminals pre-installed to make connections as easy as plugging it in.

For those installing aftermarket gauges, to avoid having to trace, cut, and splice into a new harness there is even a connector provided with all of the requirements you would need: gauge power & ground, back light power & ground, tach signal, coolant temp, oil pressure, and fuel level.

The best part is, these harnesses come with an in depth, easy to follow, 150+ page manual (broken up into 3 parts: Engine, Interior, Tail) that outlines and follows an actual install step by step.

Each wire is covered in extensive detail as to its color, gauge, information printed on the wire, its purpose in the harness, where the wire comes from and where it’s going.

Numerous full color diagrams and pictures document each step of the install and also cover different alternatives to things such as connecting to an EFI harness, converting to an aftermarket ignition system, upgrading to a newer alternator, installing aftermarket gauges, etc.

INCLUDES:

Wiring for all lighting, radio, gauges, lighter.

Main wiring harness with the fuse box and interior bulkhead.

Engine harness with firewall bulkhead.

Tail section harness.

2 front turn signal pigtails.

Charge indicator pigtail.

Parts bag with loose terminals, grommets, etc.

Alternator wiring parts kit.

Engine harness manual.

Interior harness manual.

Tail section harness manual.

Some factory installed options that would have no use in most installs have been omitted from these harnesses.

OPTIONS THAT ARE NOT SUPPORTED ARE:

Factory A/C wiring is not included, as this option seemed to almost change year to year.

This harness DOES include the power wire for the A/C switch to make it as easy as plugging in your original A/C harness, an aftermarket reproduction harness, or an aftermarket A/C system.

This harness DOES include a new blower motor harness for those with heat only systems.

Wiring for factory power window/locks is not included but available as a separate part number. Painless part # 30715 is a factory style power window/power lock harness for these vehicles if a replacement harness for this option is needed.

This chassis harness DOES include the power wires for the power window/lock option making it another easy plug in to a factory power window/lock harness or the Painless Power Window/Lock Harness.

This harness replaces all of the original wiring to the window motor, lock actuator, and lock switch found in both doors, as well as the harness that goes from the console mounted window switch to both doors.

Not only does this harness cover all the factory connections, it also comes with 4 SPDT relays pre-installed to take all of the high amperage power wires for the window motors away from the power window switch, a common upgrade many owners of these factory systems usually piece together on their own.

These relays replace the factory single relay and now send direct power to the window motors without the amperage having to go through the switch, resulting in longer switch life and in most cases, quicker up down functioning of the windows.
