fuel injector harness question....

[demonheavymetal]

upgrading my overworked stock fuel injectors. planning to run ls2 corvette injectors, but what style/type harness adapters will i need? truck is 06 gmc 4.8L currently with stock injectors and harness.

Should be a factory plug in. You shouldn't need a different harness.

you can cut off the factory truck injectors and solder on some ls2 connectors.
or, i cant remember the site, but there are some multec to ev6 (i think) injector clips.
they are definitely not a plug n play, drop in injector.

also, be sure to test fit each side of the injector in the fuel rail and intake manifold to be sure the injector is fat enough to seal.
or we could be reading a post regarding a P0171 code lol.

we sale the clips if you need them, but not the adaptor, both sides.

oh ya, don't forget to adjust the tune, the ls2 injectors are quite a bit bigger.
if the truck has high ltrims due to wear and tear, then the extra fuel might be ok and run fine, if you have a clean fuel system, the pcm will set a rich condition code.
