5.7 Ram Jet '02 S10 Blazer 4X4 Conversion I know this is supposed to be a LS1 Swap Forum but....where better to ask about the Gen III PCMs then you guys 
I have some much needed PCM Pinout/Wiring questions
I'm doing a 350 swap in my S10 Blazer in the sig. I'm building a vortec 87-up 4-bolt long block as we speak. I plan on using the 350 Ram Jet induction due to the fact that 19lbs/hr and poppet style injectors are not going to cut it. I have the LS1 style PCM and want to adapt it to the Gen 1 SB. I was wondering if anyone has ordered a harness from a '02 2500 Express Van (which had the correct harness) directly from GM. The reason is...speed scene wanted $1000 plus a core harness or $1795 w/out the core. That's rediculous!!!....I can buy a whole stand alone system for that! If I had a PCM pinout diagram for the '02 Gen III PCM with the 5.7 vortec engine...that would help me out. I'm still waiting on some info from current performance wiring on prices...(hopefully cheaper than Speed Scene) The stock CSFI poppet setup I can easily rewire for the individual Inj. on the Ram Jet. I would probably just wire the two extra injectors in if I had the '02 Express 2500's PCM pinouts but nobody seems to have it 
Any help you guys could offer would be very appreciated.

Yeah....I figured that....he still made the effort I found the pin-outs at AlldataDIY...I just bought a subscription for a 2002 express 2500. Ram jet manifold came in today...I wish it was polished...guess I have some work to do. I haven't even bought the swap stuff yet.

We can make that harness if you need it. I've done that same setup on a 454 big block.

PM me with a quote LS1 style PCM ('02 s10) to 2002 vortec 5.7 (none LS motor) I want to retain the factory harness. So this one will be from scratch. I'll need to get you the specifics of coarse for the Ramjet FI...MAP placement...etc Thanks,
Chris
