95 LT1 into 93 TBI van

I just picked up a 95 LT1 Cop car engine. Iron head. I have the complete engine, wiring harness, PCM and accessories. I just scored a set of factory service manuals for the 95 Caprice off Ebay to go with my Astro manuals. The wiring harness is very intimidating. Much different than my CPI to TBI conversion. Does anyone have any write up about your LT1 swap and/or pics? Mainly I need a starting point. How much of the harness will I need to use? How did you mount the accessories? Do you know how much crap I can get rid of on the engine? This damn thing bent my engine stand it is so heavy. All I need emmission wise is cats to pass inspection. Thanks for the help.

Thanks Joe. I looked through the archives and couldn't find anything. Hopefully I just missed it. It's my understanding that the 95 I have is OBD 1. Or what some would call OBD 1 1\2. I also found that the Corvette (yours) and the Caprice (mine) have different acc brackets. I'm assuming your AC and alt are on the drivers side where mine are on the pass side. I'm thinking the vette brackets would be easier.
Thanks Joe. I had allready checked the numbers. But the big 5.7 on the back of the block let me know it wasn't the baby. Still checking on the PCM to see if it is 95 or the OBD 2 96.
The PCM is a 16214399 which is the 96 OBD 2 model. My motor also has a crank position sensor. So I guess I should assume I have an OBD 2 setup. Apparently the one you mention, 16188051, was for the 94-95 setups. I guess mine came from a late model 95.
You asking for the wiring diagrams Alex? I don't have them yet. Other than the stuff I have found on the net. Manuals are not here yet. Here is what I have.
