Engine Wiring Harnesses Installation Instructions (91099024)

Installation Tips

Has connections for both the 4L60E and manual 6-speed transmissions. ECM programming will need to match transmission style.
Common aftermarket fuel pump and fan relays are included. Fan relay has a load rating of 30 amps so it can handle most fans, however if the fan requres more current to operate then the relay can be replaced with a 40 amp relay from any auto parts retailer.
These harnesses feature all of the connection points necessary to run the engine and transmission if applicable. The emission equipment has been eliminated and only the needed connections to run the engine and transmission are incorporated.
ECM programming will need to be done to remove all of the unneeded trouble codes that may be active from the stock application. Programming will need to be done to remove VATS (vehicle anti-theft system) programming, otherwise the engine will not run. These wiring harnesses do not include any type of VATS module to defeat the theft system.
Standard length harnesses are 54" from the back of the engine to the PCM connectors. Extended length harrnesses add an extra 4 ft. to remote-mount the PCM in your glovebox or underneath your dash.
