Default 2000 Blazer engine harness diagram?

Can anyone help me as where to find a engine harness diagram for a 2000 chevy blazer with a 4.3 vortec. I recently had to replace a head gasket and am wondering if I connected all the plugs back in the right spot because now it won't crank.

Did you ever find the diagram? I'm experiencing the same problem and I got 1 connector without a home and can't find it. I thinking that's why it won't start.

can you take a pic of the plug? they are all shaped different so even people like me can get them hooked up right.

it comes out of the main wiring harness, it's not part of the air filter system nor throttle body. It's closer to the driver's side as you can see on the picture.
Thanks for your help

I just pulled the valve covers on my 2000 today and I think I removed that same wire it was the temp. sensor in the drivers side head just above the spark plugs. hope this helps.

Thanks, I didn't see because I guess when they did the heads at the machine shop it broked off and only the screw in part of the sensor was left. Will that cause my engine not to start as if its not getting spark???

If the computer doesnt know what the engine temp is, it wont know what the fuel mixture should be. you should have a code. That doesnt look like the oil sender to me. I think its the temp sensor
