If you have a 2003-2004 LB7, and want to no-fuss easily upgrade to a 2004.5-2005 LLY, it is as easy as sending us your LLY ECM.
For converting a 2003-2004 LB7 to a 2004.5-2005 LLY, all you have to do is unplug your LB7 engine wiring harnesses, plug in a factory 2004.5-2005 LLY harness, and swap to a 2004.5-2005 LLY ECM. You do NOT have to send any harnesses to us, all that is required for this particular swap (03-04 LB7 to 04.5-05 LLY) is custom ECM programming to correct the fuel gauge. If you use a stock LLY ECM calibration, the fuel gauge will read backwards.
NOTE: This is only a custom ECM programming service to correct the fuel gauge calibration. It does NOT include any wiring harnesses or other parts.
