Is the 8.1ltr engine harness the same as a 6.0 harness(1999-2006)? The motor is a 2002 8.1... This is my first time dealing with a 8.1ltr. Does it have coil on plug? Does it us the LS type PCM? Is it Drive by Cable or Drive by Wire?
For some reason I keep thinking it's the Big Black Box Vortec type controlled engine...
Im going to work on it this week. Just curious as to what I can expect...
