Question Getting Knocked Around

I installed a 2001 4.3 (W) in my 1999 ZR2 also 4.3 (W). Everything but the Knock sensor hooked up fine. The new 4.3 has a (2) wire connection, My W/H has (1). Anybody Have any ideas. I have the old sensor pluged in and grounded. But the scanner shows low voltage or a single knock sensor present. HELP

What PCM are you using? The 99 or the 01?

Re: Getting Knocked Around

I'm useing the original 99, If I can access a wiring diagram of 99 & 01 I hope to be able to use the (2) wire (01), knock sensor that is on the engine block, but I don't know. I've always been told; You can put wipers on a donkey's butt if you hook it up right!
