Going to be putting these 60lb injectors in my 2003 Cavalier. Only question is, is what adapters do I need to connect these to the stock injector harness?

These injectors come in EV1 or EV6 style.





"You can only feed them semen for so long before their legs fall off."

I think you need the harness they came off of, and splice that into the stock 03 fuel injector harness. I believe thats what Im going to have to do with my Stage 2 Cobalt injectors in a few weeks.
Might want to also check on the ecotecforum site, a lot of the guys there have gone supercharged and use the 60lb injectors.


04 Cav. 2dr. 5spd. My DD. 'Nuff said.

your going to have to pick either ev1 or ev6 style injector. its not going to matter. there buy the corresponding fuel injector harness then splice it to your factory harness. this is what i did. cut the pig tails off both harnesses and solder and shrink wrap them together.
