1.0 INTRODUCTION We at Painless Performance Products believe you have purchased the most up-to-date and easiest to install automotive fuel injection harness on the market. All components to this harness are new. All harnesses are tested for faults before they leave the factory floor. This harness is designed for easy installation, even if you have no electrical experience.
3.0 TOOLS NEEDED In addition to your regular tools, you will need, at least, the following: Crimping tool NOTE: Wire stripper Continuity tester CAUTION: USE A QUALITY TOOL TO AVOID OVER-CRIMPING. DO NOT USE A TEST LIGHT TO TEST THE COMPUTER OR SENSOR WIRING. YOU WILL DAMAGE THE COMPUTER. Electric drill 1 5/8" Hole saw (for the rubber grommet in the firewall) 4.
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.

5.2 ROUGH INSTALLATION CAUTION: Note: Make no wire connections or permanent mounting of any kind at this time. 5.2.1 5.2.2 Position the computer and sensors in their intend locations. Drill a 1-5/8" hole for the firewall grommet near the computer for the engine group and tail section to pass through. Route the engine group and tail section through the hole. Push the grommet (already installed on the harness) into the hole until it is seated. Route the dash group over to the driver's side of the car.
CAUTION: BE SURE THE IGNITION IS OFF WHEN YOU RECONNECT THE BATTERY OR YOU WILL DAMAGE THE COMPUTER. 6.0 GM 97 - 99 LS1 SYSTEM WIRE HARNESS INSTALLATION INSTRUCTIONS 6.1 CONTENTS OF THE 60506-7 & 60508-9 WIRE HARNESS KIT Take inventory to see that you have everything you are supposed to have in this kit. If anything is missing, contact the dealer where you obtained the kit or contact Painless Performance at (817) 244-6898. The kit should contain the following items: ~ ~ ~ ~ 6.
D. Locate the Orn/Blk and Blk/Wht wires in the dash group. These two wires are for the Gear INDICATOR Switch, NOT the Neutral Safety Switch. If you have a GM column then you can use the combination switch Delco P/N D2286A 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: G. FAILURE TO WIRE THIS SWITCH CORRECTLY WILL RESULT IN A DANGEROUS SITUATION ON THE VEHICLE. If your vehicle has a pressure type brake switch, you may use a relay as shown in Figure 6.3. The relay must be a SPDT Relay and wired correctly or it could result in a dangerous situation with the vehicle. The torque converter may not unlock. The wire labeled FUEL TEST is a test point for the fuel pump. After the vehicle has been wired and tested OK, tape off this wire and store it in the harness. H.

6.3.1 6.3.2 6.3.3 6.3.4 Before you connect any wires, separate the tail section from the engine group and place it out of the way. Connect the two ring terminals labeled STARTER B+ with Red wires to the large battery terminal on the starter solenoid. Locate the three large ring terminals with Black and Blk/Wht wires and ground them to the engine. Using Figure 6.11-6.25, and the specific connections indicated in Table 6.2A or 6.2B, connect the wiring as directed.

FIGURE 6.25 IAT Sensor 6.4 TAIL SECTION INSTALLATION 6.4.1 Locate the tail section that you earlier separated from the engine group. Begin routing it towards the rear of the vehicle. Be sure to avoid all sharp edges, moving or hot parts, or anything else that may damage the harness. 6.4.2 If you ARE using the 4L60E transmission, route the 13-position connector to the transmission and attach it. Tape up the reverse lockout and skip shift solenoid connectors and store them in the harness. 6.4.

FIGURE 7.1B 60508-9 Fuse Identification 7.1 THE "CHECK ENGINE" LIGHT Normally, the "check engine" light should come on when the ignition is turned on, then go out a few moments after the engine starts running. If it reappears, or stays on while the engine is running, the computer has detected a problem and a trouble code has been set.
