Painless Performance 60505 - Manual (Page 6)

To keep the check engine light from coming on you will need to plug in a canister purge
solenoid and air pump relay to the wires in the dash section. (The computer looks for
signals from these controls and does not care if the actual devices are installed.)
4.2 YOU SHOULD GET TO KNOW THE PARTICULAR ENGINE YOU ARE
USING:
NOTE: The 94 & 95 LT1 engine has two oxygen sensors, one on the right side and one on the left side
of the engine. This system has four rectangular connectors at the computer. A 16188051
computer is required for proper operation.
4.2.1 PPPI recommends the use of the following parts. See Table 4.1. 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 right side. They must
be no further apart than the wiring will allow (approx. 16 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.
