like title says will the stock ss/sc injectors plug into the injector harness of a 2003 2.2 ecotec grand am?? plug in play???

thanks for the help

 

yes steven. 2.2 ecotec means yes. Just got to make sure you got the right wiring harness. It's definitely not plug and play without the right wiring harness.

 

i know they will work for the engine i just need to know if the stock wiring harness will plug into them

and by chance did i give u my stock harness brad? lol

 

they 36lbers and the 42lbers will fit right into their stock harness no problem, only issue is the 2003 has a different fuel rail. If you convert to a 2002 ecotec fuel rail they will fit with no issue. the 03 fuel rail uses the skinny style injectors where as lsjs and the 2002 ecotecs use the chunkier style injectors.

so yes they will fit right into the stock harness no problem but they won't fit in the head correctly. Go to a junk yard you can find an 02 fuel rail for pretty cheap.
