How to pass wire through door grommet?

This one is going out to installer of music and security .

when running additional wiring for door lock actuators and door speakers through the door how do you get the wire to pass through the original rubber grommet ? or do you make a hole and pass to on the outside and just tape it up ? what would be the neatest installation?

I have a 90' sentra.

the boot is full of wires and there is hardly any space to pull 2 wires through (for audio).

i have already pulled one through about 3 years ago with a fish wire and it took me abou 2.5 hrs to just pull 1 wire for a door actuator. it's a pain to work under the dash and inside the door !!!

I'm not sure what your door boot looks like, but mine has a molex plug....a male and female part (one on the inside and one on the outside of the door).  The molex plug has a bunch of holes in it for the existing wires.  I had to run wires through the boot for actuators, and a window module.  Needless to say, I needed a lot of room in the molex plug.  I was able to separate the plug, and drill a hole in the side that's inside the door, then fish the wires through that.  In terms of getting the wires through the boot, I taped them very tight to a rubber bike cable type thing that I could push up through the boot, then I was able to grab it under the dash and pull the rest through.  I've also used thicker wire, although that's not as stiff.  (like 10awg).

mine is sort of like a bicycle tube with enlarged grommet at each end . it doesn't seem to have a ny sort of connector to disconnect the wiring - makes me wonder how will you remove a door if the wiring can't disconnect .

 definitly no more wire will go through and if i force it i'm afraid i may damage the existing one.

Try using a 14" zip-tie. Tape the wires to it and gently feed them into the door.
