#26033 GM style LS 1 Engine Harness

$786
$20

This LS 1 engine harness is a simple, stand alone EFI engine harness designed for the mass air fuel injection system found in 1999-2004 Corvettes. It comes complete with factory connectors, terminals, color coding OBD II connector, check engine light and plugs directly into the factory computer.  This harness allows you to run the harness in the central tunnel so that the computer can get mounted in the cockpit behind the dash. 

Applications

·         Any car using a GM LS 1 engine with electronic throttle cable and mass air EFI system.

 

Technical Notes
·        
If using a new computer then the computer must also get programmed by the dealer with a 99-04 Corvette manual transmission program.

·         The computer must still get sent to Factory Five to get flashed.
·        
This is a Mass Air harness like the factory Corvette harness not a speed density harness.
·
