It could swap into just about anything. Felt like good quality, no need to spend $800 for an equivalent harness. Started right up today without a single issue. $80 harness $20 junkyard ecu, $50 base tune, car was running right away. Only complaint actually is the fuel pump relay situation, it’s only half wired. The instructions cover that but, mine didn’t have the connectors. It would be nice if there was a better solution there, but not a big enough issue to take a star away. Will definitely continue to order this harness for my swaps. Review: Works great - I did the YouTube mods and it has worked great for me. Running a 01 6.0 in a mud truck great. ## Features - A COMPLETE WIRING HARNESS KIT - This LS swap wire harness kit includes all engine and transmission sensor connectors, dash connections, which include speedometer, tachometer, park neutral, malfunction indicator, TCC, a DLC port. - COMPATIBLE WITH THESE ENGINES - The harness kit is designed to be a complete wiring harness for fuel injection system on GM 1999 2000 2001 2002 2003 2004 2005 2006 Vortec engines with Drive by Cable throttle body and 4L60E or 4L80E (with adapter) transmissions. - COMES WITH DETAILED INSTRUCTIONS - The wiring harness is designed to mount under the dash or in the kick panel on the right side of the vehicle.

Recommend buying if youre on a budget but you will have to repin.
