Alright i need a new ecu for my 1997 z24 cavalier 5 speed SERV.NO. 16228016 CCYM
HDW NO. 16204850 CCYM. I have found ecus on ebay but known of them match CCYM what does this mean? Do i have to get one that matches or do i just have to match serv n hdw numbers? Thank You all
Get it from the same year car, I don't think numbers really matter, just make sure its the right year/engine/trans combo
Have a nice day.
