I have a 95 blazer and when I got it, someone was in the process of taking out the motor. After a rebuild and getting the motor in... the last thing I have is a knock sensor or a temp sensor. Looking at the motor the left side has a knock sensor (one without wire) in the head and a temp sensor in the intake. on the right I have a hole where I think the knock (with wire) goes but its also goes to coolant so it could be the temp... who knows? I need help. both look like they go their due to the wiring. This are different heads. Where there two holes?

Plz Help!!! Quick!!

 

i have a 98 blazer and the temp sensor was on the driver side just above the exhaust manifold (had to replace it) not sure about the knock sensor maybe that will help you. i have one of the manuals if i can find it i'll post later
