Painless Performance 60505 - Manual (Page 10)

WHEN THE KEY IS IN THE START AND RUN POSITION. This is the power wire for the fuel
injection harness. If the pink wire is connected correctly, the check engine light will come on when
the ignition is "ON or START".
D. Locate the Orn/Blk and Blk/Wht wires in the dash group. These two wires are for the Park/Neutral
INDICATOR Switch, NOT the Neutral Safety Switch. If you have a GM column then you can
use the combination switch P/N 15679680 and wire it as described in paragraph 2 or 3 below.
The ORN/BLK wire needs to be grounded in "Park and Neutral" and ungrounded in "Drive". This
can also be done with a toggle switch or a switch on the parking brake.
CAUTION: DO NOT CONNECT THESE WIRES USING DIRECTIONS FROM DIFFERENT
PARAGRAPHS. YOU MAY DAMAGE THE COMPUTER.
D.1. If you are NOT using a vehicle speed sensor (VSS) or Park/Neutral Indicator Switch then you will
need to connect these two wires together.
Note: If you do this, the computer will stop controlling the exhaust gas recirculation (EGR)
solenoid. THIS WILL PREVENT THE SYSTEM FROM BEING STREET-LEGAL.
D.2. If you are going to use the recommended switch for the computers benefit ONLY, then you will
wire it as shown in Illustration A.
D.3. The recommended switch is a combination reverse light AND neutral safety switch. You may use
it for these purposes AND the computer signal IF you wire it EXACTLY as shown in
Illustration B.
D.4. You may want to install your own switch. This switch must connect the Orn/Blk wire to ground
only when the car is in PARK OR NEUTRAL. You may or may not want to use the Blk/Wht
wire. The other end of the Blk/Wht wire is already grounded throughout the harness.
E. The single light blue wire is the wire that lets the computer know when the brake is applied. If you
ARE NOT using a 4L60E then you will tape off and store this wire. If you ARE using the 4L60E
transmission then you will have to install an electrical switch described in Paragraph 4.1.2. The pink
wire provides power for this switch.
