I RECENTLY GOT a knock sensor for a 89 full size van, and put it in and it fixed my false spark knocks. [82 are junk]- and i also picked up a newer stye E.S.C MODULE. - but my books i have stink for trying to wire it up correctly. for wire location at new esc modul.------ I have my wires down for color [82 z/28], but not sure where they go on new esc module.------i know i get no knocks now, but if you unhook the esc while running,, it doesnt set code, and the idle i been fighting in park smooths out ?-- does this sound like deffi, module is acting up. ? sounds like it.

 

Carl, you don't mention what your setup is? These Knock Sensors are not necessarily directly transferrable from one system to another, even if both are 350s.

 

im a 355 1982 z, with crossfire, AND now has a 7747 ecm.with prominator,-- And thats why i went to newer knock sensor, to work with 7747 ecm. and thats why i wanted info on the ESC, AS i stated in first post.--------Sorry if i posted this in wrong section.

 

Hopefully someone here can help you. Also, try the Tech/General Forum.
