It is possible to adapt the harness you have. The only problem is the pcm is routed to mount on the driver side with the vortec harness. On the blazer and s10 platform it is routed to mount on the passenger side. You may be able to just pull the main trunk line to the other side, or just mount the pcm on the driver side of your blazer.

We offer brand new plug and play harnesses for your application. If you have any more questions feel free to post up. Ill be keeping an eye on this thread for ya!

You could flip the harness over and repin the inj and coils for the bank switch. Of course a few connectors would need to be lengthened to suit, but the truck harness is extra long and easy to work with

The harness we build for that application is $700. It will be 100% plug and play if your using some form of factory fan set. If you are using universal you will have to splice the fan power. Thats it.

We use production tooling to achieve a consistent, reliable solderless crimp. We also use gm color codes, along with the TXL wire used in a factory harness.

Feel free to call if you like or email.

Lowrolr,

Here are the gage cluster schematics....

www.psiconversion.com/diagrams.html

Just to note, we are in the process for adding a lot of schematics for various applications so customers can pinout their gage sets themselves (this is one of the more common questions people as when it comes to there swap) as well as retain ABS, and other system functions. Our dyno shop recently installed one of our harnesses in a 2003 S10 with our standalone harness and it was effortless (dont want to say painless) and all the S-10 functions were retained.

If you need more information let me know. Hope this helps.

Jon
