I got it all smogged last month. Was actually very easy, the only thing stopping me right off of the bat was the lack of EO number on the Air Raid air filter.
I was actually so impressed, or surprised by how little the ref knew, that I plan on taking my four more ASE exams to get the cert. so I can appear more competent to him. He didn't understand my wiring when I told him I went through the EECS program at Cal.
I used the original truck wiring harness out of the donor, as well as the original computer. No re-programming, or changing anything. Just hooking up the right wire to the right spot, and everything is well.
