As long as it's unplugged and you haven't applied power to the SRV it should line up and go right back on Ed.
The injectors aren't polarity sensitive,so it doesn't really matter which way you apply 9 volts to them. If you have a wrecking yard close by,you could just cut the harness off an injector and use it,but all i've ever used is a set of small .187" female electrical clips,that'll push on the male part of the injector.

Or these with a short chunk of heat shrink over the metal ends,just to keep them from shorting out if they happen to touch,not like a 9 volt battery will create any damage,just more for peace of mind
