The Stock Harness

After removing the dash and tagging all the wires, see the Dashboard" section, unplug the rear tailights from the fuse box. You may want to remove the brake pedal and booster, see the "Brakes" section, for easier access. Disconnect battery. From the motor side of the firewall remove the bolt in the middle of the fuse box. Pull on the wires this will unplug the headlights, wipers, alternator, and starter. From the passenger side of the firewall unscrew the two screws in the fuse box. The fuse box is now disconnected from the car.

Lay the wiring harness out on a work bench. Using
a small pair of scissors cut away all the tape holding the wires together.
Working from the furthest wires out work your way back to the fuse box
cutting away wires you no longer need. Be careful when cutting out ground
wires. They all interconnect at a point halfway down the harness. If you
cut the connection out you will end up having to solder a dozen ground
wires back together. I removed all the interior lighting, the radio and
speaker wires, the heater and a/c wires, all the wires to the gages in
the center of the dash. I only kept the wires going to the brake pedal,
steering column, and the speedometer printed circuit. I removed the wires
from the printed circuit that indicated oil, temperature, and fuel. I will
be installing new gages with the racing accessories harness. Tie wrap the
wires neatly back together. The wiring harness is now only 2 feet long.
Remember to leave the main heater wire if you plan on using it for the
racing accessories (not recommnded).
The back up lights will need to be routed to a switch
on the dash or to an automatic switch on the new shifter. B&M shifter
reverse light switch is an added option.
Next remove the oil and temperature wires from the
harness in the engine compartment along with heater and a/c wires and any
other redundant wires. Re-install the fuse box, plug in rear lights. From
the engine compartment plug engine compartment harness into back of fuse
box and tighten bolt. See the "Brakes and Steering Column" sections for
further assembly. Price $0.00
Racing Accessories Harness

After installing each fuse I run wires to individual
swithes on the dash. LED lit switches are recommended. The purpose of running
individual switches from a remote fuse panel is to be able to perform two
main functions (providing you did not opt to use the heater wire). First
the temperature gage, water pump, and cooling fan can be left on to cool
the car down between runs. Secondly, by switching off the ignition, you
can still bump the motor over with the starter without the engine starting.
You then run a wire from each switch to its corresponding
accessory. The line lock switch is located on the shifter shaft, see the
"Line Lock" section.
The price will vary depending on accessory locations
and amount of wire used. I purchased my fuse box and switches from Cole
Hersee and the bulk wire I bought for 20 cents a foot at my local auto
parts store. You can purchase 4 basic colors. I bought 20 feet of each
color. I also recommend soldering all connections to protect against vibration.
The six connectors I used from my MSD multi spark kit. Total cost $68.00
