HELP!!!!! Wiring harness attached to firewall! 
I drilled a hole in the lower-right corner of the plastic thing that looks like a plug to run a wire and knocked off what looks like a teal wire inside the harness. I started the car, started right up, but the ABS INOP light is now on. My wipers also don't work anymore. The only reason I found out I took out a wire or two after drilling is cause when I took the drill out of the hole, I found some teal on the bit along with copper wire strands that are in a wire.
Obviously, I know where the problem is. The broken wires are inside that plastic piece that looks like a plug, and is holding all the wires in place. That being the case, I can't get to them!
Does anyone know how to open up that plastic piece so I can maybe repair the wires myself? Thanks in advance.

I drilled from underneath the dash (left from the brake pedal). I didn't drill the car's metal. I drilled into the plastic thinking I can sneak an extra wire or two for my fog lights and amp (the alarm guys drilled into the plastic for the alarm wire and amp wire few years ago. I wanted to make it bigger for the larger 8 gauge amp wire I upgraded to so the plastic can be a flush seal to the firewall).
If you look under the dash, it is a black/gray plastic about 2" x 2" which looks like a plug.

Hit up a PC repair shop. They should carry some PC customizing tools. You will be looking for a molex pin removing tool. Looks like a small thin punch. You will push the tool on the pin in the harness. This will release the pin and allow you to pull it out along with the remaining damaged wire. You will need and new pin of that same size. (PC shop should have these as well) Cut and crimp on the new pin to the remaining wire and snap it back into the harness. No tool needed for that. Snaps right in. If the shop doesn't sell those exact size pins, be VERY careful when removing the original one... you may be able to bend it back into shape and reuse it..... but not likely.

Thanks for the help, but I made an appointment to get it flat-bedded to an electrical repair shop and pray that they will be able to fix it. Car is still drivable, but I don't want to take the risk since the shop is 20 miles away. I will drive it onto the flatbed rather than having it pulled however.
What I mean by fix, is being able to dig into that plastic and repair the damaged wires since the damage is inside the gray/black plastic piece that looks like a plug and mounts to the firewall. It might not even be a plug after all, just something to keep all the wires in one place. In fact, I can't even see how the engine side can detach from the under-dash side. You do know what I'm talking about, right?
A bonus for me would be able to get them to bunch up the remaining wires (alarm, amp, fog lamp). I will ask when I go.
