It can be very tight on the cabin side of the grommet/diaphram so it could be useful to slide a 12 guage solid copper wire through at an angle and be sure you can see it inside the cabin. Tape the jammer head wires to the copper wire and pull it through slowly and carefully. It's easier if you have someone on each end.
note......when punching through the grommet, be very careful not to allow the screwdriver to go past the grommet......only far enough to get through the grommet. You could damage something inside the cabin if you allow the screwdriver to go too far.
In my car (Honda CR-V), the bundle is on the passenger side right about even with the passenger's toes.
Hope that helps.
