S&P LS-1 wiring harness plugs into
the engine, trans and computer, then has four wires to hook up.
One to the key, one to ground, one to fuel pump and one to
starter. Harness comes complete with front and rear O2 sensor plugs for
full emission applications.
We mounted the ‘99 LS-1 computer on
the passenger side inner fender. This computer is
weather proof and can be mounted inside
or outside of the vehicle. Street & Performance
reprogrammed the computer with the proper gear ratio and tire
diameter.
The type of computer is determined by the
wiring harness that is used. You can put a ‘98 harness
and computer on a ‘99 up engine or visa versa.

Next the new Street & Performance
wiring harness was installed. This harness has all of the
connections labeled for easy installation. S&P will custom
make a harness to any length. The harness is available for
‘97 up Vettes, ‘98-’02 Camaro/TA and
‘99 up 5.3, 6.0 and even the big block 8.1 engines,
manual or automatic transmissions. Shown left is the S&P
air cleaner with the built in MAF (mass air flow) sensor. The
air cleaner is available for either 3 pin or 5 pin MAF sensors.
Air cleaner elements are washable and available in 1 3/4, 2
1/2, 3, and 4 inch widths.
Tighting the clamps to the steam line
hose coming out from under the throttle body and tee’d
into the upper radiator hose. This is to release hot spots from
the upper portions of the heads and to also pass through the
bottom of the throttle body to
prevent icing in cold weather. The Grand
National radiator and electric fans where used with a
adjustable thermostat from S&P to control the fans instead
of the computer. The temperature is taken from the bottom of
the radiator, so that when the bottom of the radiator reached
170 -185 degrees, the fans are turned on. We also tied into the
AC so that when it is turned on it will turn on the fans to
pull air through the condenser.
If your exhaust system does not have a
provision for the O2 sensors, S&P can provide you with an
O2 bun that can be welded into the exhaust. S&P also
carries AC Delco sensors for your application. The front O2
sensors are needed in all applications, but full emission
vehicles will need the rear O2 sensors located behind the cats.
After fitting the dual exhaust pipe with
two Flow Master mufflers, the exhaust system was removed
for S&P to thermal coat it inside and out.
