PRE-INSTALLATION AND HARNESS ROUTING GUIDELINES
The installation of your harness kit will consist of two parts:
~
The physical routing, positioning, and securing of the harness, wire groups, and individual wires and
connectors.
~
The proper electrical connection of the individual circuits.
We cannot tell you how to route the harness in your automobile. That depends a great deal upon the particular make
of the automobile and what extent you want to secure and conceal the harness. We do offer some general guidelines
and routing practices starting in
Paragraph 5.3
, general installation instructions in
Section 5.0
, and precise
instruction concerning the electrical connections you will have to make beginning in
Section 6.0
. To help you begin
thinking through the installation of your wire harness, read the following sections:
4.1 TRANSMISSION
FUNCTION
If you are not using the 4L60E transmission, read
Paragraph 4.1.1
, then skip to
Paragraph 4.1.3
. If you
ARE
going to use 4L60E, then skip
Paragraph 4.1.1
, and start at
paragraph 4.1.2
.
4.1.1
If
you
ARE NOT
using a 4L60E transmission, tape off and store the light blue/black and pink
(brake switch) wires in the dash group and the 13-position (transmission) round connector in the
tail section.
4.1.2
If
you
ARE
going to use a 4L60E transmission then you
MUST
have a two-position vehicle speed
sensor (VSS), and the correct brake switch. These are necessary to make the transmission work
correctly. The brake switch should be closed (electrically connected) when the brakes
ARE NOT
being applied and open (not electrically connected) when the brakes
ARE
being applied. This is
the opposite of a standard brake light switch. If you are using a pressure brake switch, a
SPDT
relay must be installed to unlock the converter when the brakes are applied. The vehicle speed
sensor lets the computer know how fast the wheels are turning.
4.1.3
Regardless of whether you use the 4L60E or not, the vehicle speed sensor (VSS) and park/neutral
indicator switch must be used and is needed by the computer so it can command the emissions
control devices on the engine. This part is necessary if you want your car to be street-legal.
NOTE; Emission devices
This harness has provisions for 3 emission devices, which are EGR solenoid, Air Pump relay and a
Canister Purge solenoid.
We have rolled up the canister purge solenoid wiring and air pump
wiring in the dash section and may be left there if these items are not to be used. If you
plan on using the canister purge solenoid and air pump you will need to route these wires
out to the engine compartment and install an air pump relay. Secure the wires to the main
harness using the tie wraps supplied.
