INSTRUCTIONS MAIN FUSE PANEL

The main fuse panel harness s designed to be mounted under the dash a the firewall in an area close to the steering column.

The enclosed representation of the main dash harness shows each circuit branch and identifies each connection by its color and

function. Follow the drawing for the individual circuit connections.

CIRCUIT BRANCH 1 HORN AND DIMMER SWITCH CONNECTIONS

1. Insure that the Horn relay is plugged into the connector. No further action is required.

2. Insure that the Dimmer switch is plugged into the connector.

3. The orange Dome Courtesy Feed wire (40A) routes to the courtesy light power feed. Most courtesy lights are activated by the

headlight switch or individual door jamb switches setting a ground connection.

4. The white Courtesy Ground wire (156) routes to the courtesy light ground. This wire enables the headlight switch to turn on the

courtesy lights.

CIRCUIT BRANCH 2-FRONT END CONNECTIONS

1. Select the dark blue Right Front Turn wire (15A) and connect it to the right front directional lamp socket. If you are using a single

front directional light with an 1157 or dual filament bulb, this wire would be connected to the high filament of the bulb.

2. Select the light blue Left Front Turn wire (14A) and connect it to the left front directional lamp socket, If you are using a single front

directional light with an 1157 or dual filament bulb, this wire would be connected to the high filament of the bulb.

3. Select the brown Park Lights wire (9A) and connect it to both the front park/running light sockets. If you are using a single front

directional light with an 1157 or dual filament bulb, this wire would be connected to the low filament of each of the front running

lights. An in-line splice of this wire will be necessary to accommodate wiring of both of the front park/running lights.

4. Select the white Coil to Tachometer wire (121). This can be connected directly to the tach terminal on a GM HEI distributor, to the

Negative side of the coil, or a tach connection in an aftermarket ignition module such as an MSD module. See the installation

instructions for the type of distributor you are using for specific connection requirements.

5. Select the pink 12V ignition wire (3A). This is the 12 volt power source for the distributor. This can be connected directly to the

distributor, as in a GM HEI distributor, to a ballast resistor as in a points type distributor, or to the ignition power source for an

aftermarket ignition module such as an MSD module. See the installation instructions for the type of distributor you are using for

specific connection requirements.

6. Select the white Wiper feed wire (93). Route and connect it to the wiper motor power connection.

7. Select the dark blue Oil Pressure Sender wire (31). Route and connect it to the electric oil pressure sender.

8. Select the dark green Water Temp Sender wire (35). Route and connect to the water temperature sender.

9. Select the light green Headlight High Beam wire (11A) and tan Headlight Low Beam wire (12). Route and connect these wires to

the headlights. An in-line splice of this wire will be necessary to accommodate wiring of both of the headlights. Using the supplied

terminals and connectors, connect these wires along with the headlight ground wires to the headlight connectors according to the

orientation in the diagram on this page.

10. Select the dark green Horn Feed wire (29). Route and connect it to the horn power terminal. If your horn has a separate ground

terminal, you must supply this ground wire as it is not included in the kit.

11. Select the orange Electric Fan Feed wire (300). It is recommended that this wire be routed and connected to a fan relay. This wire is

the relay trigger connection and should be connected to terminal (85 or 86) of the relay.

3. Select the light blue Third Brake Light wire (17B). If you are using a third brake light, route this wire together with the white Brake Switch wire (17A) and connect them both to the output side of the brake switch. If you are not using a third brake light, the light blue Third Brake Light wire (17B) should be taped back against the harness and left unconnected or removed from the main harness.

4. The main power input wire from sub kit 910-64027-4 is plugged into this connector. Connection descriptions are described on page 6.

CIRCUIT BRANCH 4- REAR BODY CONNECTIONS

Route the rear body wires to the rear of the car and connect as follows:

1. Select the yellow Left Rear Turn wire (18) and connect it to the left rear directional lamp socket. If you are using a single tail light with an 1157 or dual filament bulb, this wire would be connected to the high filament of the bulb.

2. Select the dark green Right Rear Turn wire (19) and connect it to the right rear directional lamp socket. If you are using a single tail light with an 1157 or dual filament bulb, this wire would be connected to the high filament of the bulb.

3. Select the rear Running Lights wire (9B) and connect it to the rear running lamp socket. If you are using a single tail light with an 1157 or dual filament bulb, this wire would be connected to the low filament of each ofthe rear running lights. An-in line splice of this wire will be necessary to accommodate wiring of both of the rear running lights.

4. Select the light blue Third Brake Light wire (17B). If you are using a third brake light, route this wire to the third brake light switch. If you are not using a third brake light, this wire should be taped back against the harness and left unconnected.

5. Select the tan Gas Gauge Sender wire (30) and connect this to the sending unit on the gas tank.

CIRCUIT BRANCH 5- ACCESSORY FEED WIRE CONNECTIONS

This kit provides 5 additional fused power circuits that can be connected through the included terminals anddisconnect as follows:

CIRCUIT BRANCH 9- TURN SIGNAL SWITCH CONNECTIONSThis kit is designed to function with a GM style turn signal switch. The connector mates to a 3-7/8” inch long plug used on GM columns

from 1969-1974. It is also used on many aftermarket steering columns. From 1975 on the GM switch used a 4-1/4” inch connector.

The connector is from the same family and uses the same terminals. By using the supplied mating connector it is easy to adapt any

GM column to the kit as the color codes and cavity locations for the turn signal switch wires are the same. Orient the turn signal switch

connector as shown in the diagram. Notice the letters on the face of the connector. These correspond to the connector cavities. The

function of each wire within the cavities is as follows:

CIRCUIT BRANCH 9- TURN SIGNAL AND HAZARD FLASHER CONNECTIONS

1. The purple Turn Switch Feed wire (16A) is a 12 volt fused ignition wire from the fuse box to the Turn Signal Flasher “X” terminal.

2. The purple Turn Switch Feed wire (16B) is a 12 volt fused ignition wire from the Turn Signal Flasher “L” terminal to the Turn

Signal Switch connector cavity “L”.

3. The brown Turn SW-Hazard wire (27A) is a 12 volt fused battery wire from the fuse box to the Hazard Flasher “X” terminal

4. The brown Turn SW- Hazard wire (27B) is a 12 volt fused battery wire from the Hazard Flasher “L” terminal to the Turn Signal

connector cavity “K”.

CIRCUIT BRANCH 10 RADIO AND HEATER CONNECTIONS1. The tan Radio wire (43) is a 12 volt fused ignition wire that can be used for the main radio power.

2. The red CB Radio wire (100) is a 12 volt fused accessory wire that can be connected to a CB radio or any other radio function

requiring an ignition or accessory power source.

3. The yellow Clock-Bat wire (101) is a 12 volt fused battery wire that can be connected to a clock radio or clock that requires a

12 volt battery power source.

4. The brown Heater/AC feed wire (50) is connected to the heater or A/C harness ignition power terminal.

INSTRUCTIONS

1. All connector cavities in the black and white connectors use a 56 series. 25 female terminal with the exception of the "spare ignitioncavity" which requires the wider 59 series .31 female terminal included in the bag.

2. After installing the proper wires into the ignition switch connectors, the white connector should be plugged into the ignition switch first then the black connector. The black connector must be plugged into the switch, as this will lock the white connector to switch.
