red/blue harness question???
I have a take out LS1 from a 2003 vette with a blue/red PCM connector. Lt1swap shows the blue/red connector going from 99-02 and the 03-07 using the blue/green pcm connector.
http://www.lt1swap.com/2000harness.htm
So is the color of the connectors more important than the model/year of the car they were out of? Do I just use the info and wiring diagrams for the red/blue connector and forget the year. To complicate things even more, I have confirmed my PCM has the chip to run this drive by cable which should be a 03 computer. So how does a blue/red harness come on a 2003 computer and car?
I am confused! Help please!

Thanks Tom for the reply!
The computer also says blue/red. What is confusing is the LT1swap diagrams say this engine/ PCM combo should never have been in a 2003 vette. As I am installing this engine in a Cobra replica I have some major mods to do to the harness. I can't do the mods until I am sure which wiring diagram to use.
The only issue is making sure I am using the correct schematic to modify my harness. So are ALL blue/red harnesses and PCM's exactly the same?
