does a injector jumper harness exist for a L31?

[Mater]

as the title said. i am still not 100% sure if i want to go carb as i have been given access to some one with HPT. but if i do i would like to use a jumper harness for the MPFI (going external injectors and rails do to the intake i already have) and i do not want to chop up the stock harness

even if a premade does not exist is there female plug end that plugs into the CPFI injector harness?

I'm a bit late, but it may be easier to cut harness and re-pin an available connector since you will probably need to fab the injector individual wires as well as injector lines.
Speak to a top line performance shop to pick brains on easiest approach.
@Fless has some good connector links he may share.

Once you identify the connector, take a look at the APTIV catalog to verify the connector:
