Installation of Interim Wiring Harness
IV. Installation of Interim Wiring Harness- Disconnect the battery.
- Locate relay bracket under dash connected to the steering column. Remove the single 10 mm nut securing the bracket and lower it.
- Install the relay connector on the interim harness into the relay bracket. To do this, line up the wide lugs on the connector with the cut-outs in the bracket. Rotate the connector approximately a 1/8 turn while pushing in to lock it into place. Use the other relay connector(s) on the bracket as a guide.
- Install the relay (P/N 6555.15) in the connector and reinstall the relay bracket.
- Locate the three wires that go to the fuse box:
1. Light gauge blue wire with plug-in terminal
2. Heavy gauge yellow wire with fuse holder
3. Green and yellow stripped wire with eyelet terminal
- Open fuse box door; route these wires along the existing wiring harness to the fuse box. Connect as follows:
1. Blue wire - fuse box connector P706F (blue), pin number B1 (bottom right), hot with key in accessory or run position.
2. Yellow wire - locate connector number P706H (2-pin black connector). Unplug the connector from the fuse box and, using a small flat-bladed screwdriver or similar tool, remove wire number 1 from terminal number 1 of the connector. Cut the terminal off the wire and strip approximately a 1/8 inch of insulation from the wire. Strip the same amount from the yellow wire; lay the two wires side by side and twist the ends together. Crimp fuse box terminal (6542.26) to the wire. Due to the size of this terminal, the proner crimping pliers cannot be used. Therefore, if an adequate crimp cannot be made, the terminal must be soldered to the wires. Reinstall the terminal in the connector and plug the connector back into the fuse box.
3. Yellow/green wire - remove the 10 mm bolt from the dash support (immediately to the right of the fuse box opening). Sand or scrape the paint from the area of the bolt hole and attach the eyelet to the dash frame with the bolt.
- Use nylon wire ties to secure these wires to the existing fuse box harness. Be sure to leave enough slack for the ground wire so that it does not get pulled too tight when the fuse box door is closed.
- Install a 30 amp fuse into fuse holder and close fuse box door.
- Locate the three male terminals on the short leg of the interim harness (wire numbers 92-94-96). Plug these terminals into the male end of connector HC6 (brown 9-pin connector) from Section III as follows:
1. Wire number 94 to pin 1
2. Wire number 96 to pin 2
3. Wire number 92 to pin 3
- Reconnect connectors HC6 and HC7A; repack wiring connector bundle into place and secure with rubber strap.
- Route the long leg of the harness along the existing dash harness where it passes under the steering column along the bottom edge of the dashboard.
- Secure in place with nylon wire ties:
Remove center console side panels (see Body Equipment Workshop Manual, Section 13, page L4.009).
Route the harness through the console, being careful not to contact heater hoses, other electrical connections, etc.
Route the harness to the right side kickpanel area along existing wiring harness for blower motor; secure in place with nylon wire ties.
Insert the three male terminals into connector HC7 (10-pin white connector) as follows:
1. Wire number 94A into pin 5
2. Wire number 96A into pin 6
3. Wire number 92 into pin 7
Reconnect connectors HC7 and HC6A, making sure that the wire numbers match. Replace the bundle of connectors and secure in place with rubber strap.
Install the three window switches.
Reconnect battery, turn on ignition, and test window operation.
Replace door panel protective sheet, if necessary (left P/N 9365.23, right - PIN 9565.24)
Reinstall door panels, console side panels, underdash wiring protectors, etc. in reverse order of disassembly
Install blanking plug (P/N 6551.20) in the unused switch hole on the right side door panel
Recommended Installation Time: 0300 hours
