So I need some advice. I had a 2005 lly 6.6l motor and I am in the process of swapping it out for a 2004 lb7. I was told it was plug in and play with just changing the nsbu switch and the oil pressure sensor. I did all that so now I am at the fuse box and my cab harness isnt the same as well as the engine harness just where it plugs into the fuse box. Any advice would help. Thanks in advance!

Show us pics of what you are talking about. You are swapping backward from what most do (LLY to LB7), but wiring is the same under the fuse boxes. You shouldn’t even have to swap the oil sensor & sensor harness unless the LB7 is an 01/02 model one wire style.
