After some headache with wiring and a 1200 mile drive to buy a new harness my truck finally fired up today. Everything works correctly save for the oil pressure sensor. The 99 harness that I am using has a different plug than the 04 LQ9 so I am going to add the right plug into the harness later on. This weekend I will be welding up the exhaust I have some sections of 2 1/2 in. mandrel bent pipe along with a Magnaflow X pipe and a set of Borla Pro XS mufflers to some 3 inch tips. This is my first swap like this and I am hooked. A lot has gone into this truck and I have to give a huge thanks to my family for all of the help along the way, Jon at APC, the folks at Nelson performance, everyone on LS1TRUCK for sharing their knowledge, and most of all the good Lord up above. Enjoy the rest of the week everybody.
