User's Manual

4.2 YOU SHOULD GET TO KNOW THE PARTICULAR ENGINE YOU ARE USING:
NOTE: The 1997-02 LS1 engine had four oxygen sensors from the factory. We have included
provisions for only two oxygen sensors, which include one on the driver side and one on the
passenger side of the engine. We have removed the two rear oxygen sensors since they
originally where behind the catalytic converters and most people don’t want to run more
than two oxygen sensors. This system has two rectangular connectors at the computer.
4.2.1 PPPI recommends the use of the following parts. See Table 4.1A for 60506-7 or 4.1B for 60508-
9. These will meet all requirements and are compatible with PPPI harnesses. The numbers given
are GM and AC Delco part numbers. You must use the computer listed on table 4.1 with our
harness.
4.2.2 Familiarize yourself with the harness by locating each of the harness groups and by looking at the
connectors on the wire ends.
4.2.3 Decide where and how the computer, fuse block and relays will be mounted. PPPI wire harness
kits are designed to mount either under the dash or in the kick panel on the passenger side. They
must be no further apart than the wiring will allow (approx. 18 inches).
4.2.4 A good exercise is to lay out the wire harness on the floor beside your vehicle and identify all the
connectors and wires.
4.2.5 You will want to route the harness through and around open areas. Inside edges provide extra
protection from hazards and also provide places for tie wraps, clips and other support.
4.2.6 Route the harness away from sharp edges, exhaust pipes, and the hood, trunk and door hinges.
4.2.7 Plan where harness supports will be located. Use a support approximately every 6 inches unless
the harness routes under the floor carpet.
4.2.8 Allow enough slack in the harness at places where movement could possibly occur (body to frame,
frame to engine, etc.).
4.2.9 The wires should be bundled into harness groups. Use tape, nylon ties or poly split loom.
