i'm working on a 2001 silverado with a built 4.3l. we want to do 3bar OS using hptuners. the problem is the truck has a older style pcm. the plug style. i went and got a 2 plug style (newer ls style) from a 4.3l astro. what i'm trying to find out is, has anyone completed this swap? i need to know if its a wire color for wire color swap, or if the wire colors are totally different. i have a pin out for the newer pcm but not the older style stuff.

Do a google search for 0411 swap. You will find a ton of info from the fullsize guys doing the swap. Pacificp.com is one site that comes to mind besides thirdgen.org and fullsizechevy

Thats mostly for v8 stuff but really the only difference you have is the OS from the 4.3 van instead of the 5.7 van. You will be short the wiring for the extra two injectors of course but should be the same otherwise
