Does the 93 Firebird computer have a knock module?

 

Yes

 

Where is it located at?

 

It does not have a replaceable knock module. Only 1994s and later have that.

 

ohhhhh ok thanks

 

You can wire in a resistor to have the same affect as the LT4 KM. I do not have the site anymore that stated how to do it.

There is a blue wire in one of the bundles near the ECM. test it and find out waht resistor is needed. Wire it in and ground one of the sides. Something along those lines is what i remember.
