Hi all, I just got done rebuilding my 4.3 in my 96 blazer. Problems arose when I had to get new block due to old one cracked. My new block is a 2001 GMC which uses a different knock sensor (2 wires) my 96 has 1 wire going to the knock sensor. Is there a way to make the 2001 work with the 1996 wiring? I can handle doing a rewire but need to know if it is possible and what to change!!
Thanks for your help, Rob

no, buy the sencers, if you want the 01's to work your in for a headach, like the whole computer and wiring harness and fuel system from the 01
