You will need the PCM pinouts for your 2000 S10 V6 black box Vortec PCM and for a 2002 S10 V6 with an automatic transmission. Move the pins / wires one at a time from the Vortec PCM to the LS1-B (12200411) PCM.

There is a forum member that goes by “Lextech” - he seems to be our resident expert on the 0411 swap.

Once that is done, then full flash the 0411 PCM with a 2002 S10 V6 automatic 2 wheel drive tune.

Like the tune attached below …….

I looked into the swap a while back. (Black to 0411) I have the 0411, but never went forward with it. I have to deal with yearly emission ODB2 inspections. I'm not sure what would happen if the emission gear would fail me due the different ECM. I figure the system status (O2, cat, heater,....) would be same between the two. But I'm not sure if the emissions gear actually looks at what OS or ECM model is installed. Any comments?

They will always read the VIN.

In CA, if vehicle is later than 2005 then they read the calibration ID's/CVN's and may possibly compare them to a database (supplied by OEM).

The connectors are different between the 16263494 (Black) & the 12200411 PCM. I seem to recall the wire pins are different. That is, it will take more than removing it from one conn. and moving it to another. I believe the pins need to be changed.

Can you post the 2002 Vortec pinout?
I found these, but I'm not sure if the Vortec OS uses the same pinout.

Do pinouts change between different OS's of the same PCM?

My stock info: PCM#: 16263494 BCC:CDND HrdWr: L35 "W" OS: 16265175

2002 was the last year the 4.3L VIN "W" was used.
The 0411 was used on the "W" from 2001-2002.
2003-2004 GM used the 4.3L VIN "X", with these PCMs: 12581565, 12576106.

I got the computer and plugs today, and..... It's gonna be a looooonnnnng satuday afternoon.
The pins are the same, but they are crimped on and only pull out the front of he plugs, so the only way I can see doing it is getting new pins crimped on after you switch plugs, or sodder each wire after u pull it out and place it where it needs to be. I'm probably gonna be soddering it. :-/
contact lextech for the pinout, he has it down to a science.

Thanks everyone,

Are you sure? Just lift the little plastic tab & push the pins out. There's no need to cut, crimp, & solder anything for a repin.

Have a look at attached pics...

(Ignore the crimper; I'm not sure how that other tool would be used, but you don't need it)
