Angry Excessive wiring under dash

Yet another post from me, thanks for all they help! Anyway I had to crawl under the dash today to pull my bad headlight switch and there is a ton of wiring under there, and there are a lot of non factory wires that I would assume, go to nothing because my Jeep is bone stock. I have a factory amp, my build sheet says I have 6 speakers(Can't find 2 of them, not in the rear doors, and I don't have a soundbar), ABS, factory fog lights, and rear window defroster. So I guess my question is, even with all that stuff should there be this much wiring? If not, could I get some help locating the stuff that shouldn't be there? Also, should I worry about pulling out any non factory wires since it doesn't appear that anyone has added anything to it that would need the wiring?Name:  IMG_20140103_220321180_zpsx8detsiu.jpg

"So I guess my question is, even with all that stuff should there be this much wiring?"

You are probably better off leaving well enough alone. No reason to reinvent the wheel if you want a model "A" or a lawn tractor just go out and buy one.

Remember where that fuse is if your transmission gets funky.

Here's a partial of my build sheet:
Auxiliary Transmission Oil Cooler
NHMP Speed Control
NMCP Heavy Duty Engine Cooling
PX8 Black Clear Coat
QX8S Black Clear Coat
RAAC All Radio Equipped Vehicles
RAFP AM/FM Cassette Radio
RCGP 6 Speakers
RDCP Power Antenna
SBAS Power Steering
SCGP Leather Wrapped Steering Wheel
SFAS Standard Duty Shock Absorbers
SGAS Rear Shock Absorbers
SUAP Tilt Steering Column
I have yet to find the other speakers though. They aren't in the rear doors or anywhere else I've looked. I just have 2 in the hatch and 2 for the front doors. It came with a factory amp too(I think). I have slightly more pressing concerns than that though, I bumped a wire and all of my speakers went silent and now my receiver won't stay on. And all the excess wiring makes it a total @#$&% to check any factory wires under the dash.

Just put a blindfold on and start cutting, what could possibly go wrong? Some of that wiring looks like it was added for a two way radio, some kind of after market crap. The factory never had huge bundles of tie wrapped wires stuck everywhere.

I'm not going to blindly remove wires. I do have another question though, the source is a black box next to my factory? amp. Is it factory?

Looks like a business or .gov communications radio.

I see you got the rear shocks, those are always a good option to get.

Also see you got speed control.......guess that means "gas pedal", good option, hate it when vehicles don't come with a gas pedal.

Really? I was intrigued because the serial number and model number were completely useless in a search. Maybe I could get ahold of Motorola and have them search it up.

Speed control is actually cruise control, and yeah they put some kinda obvious stuff on there. But the build sheet was helpful, I found out I have the tow package, factory aux trans cooler, and apparently a skid plate package:
ADL Skid Plate Group
AHT Trailer Tow Group
And of course, power everything, which is more of a pain than a luxury.

Could also be the transceiver portion of a really old wireless phone.
Yep;

Yep, indeed!

What you have there is the in-car transceiver for an old flip-phone. It's analog & TDMA, and neither technology is in use any more. It's a paperweight. Not even a museum piece. Worthless.

Basically, you installed this unit in the car permanently, with an external antenna. It had a transceiver (that's what you're seeing in there) and a cradle where your flip phone could be plugged in. Optionally, you might have had a hands-free setup, which would have included a speaker (about a 2 1/2 inch by 4 inch box) and a microphone.

This setup enabled the hand-held phone to be boosted to the full power of an installed phone (3 watts vs. .6 watts), and also gave the advantage of an external antenna.

This was important back in the day when networks were optimized for installed phones.

The connector on the end has two cables coming out of it. One goes to power (should have power, ground, ignition sense, and horn alert), and one goes to the cradle for the phone.

There should also be a coaxial cable coming out of it. Motorola insisted on using a crappy mini-UHF connector, while everybody else used the far superior TNC type.

There! More than you ever wanted to know about it!

The bottom line is this: Feel free to trace the wires, disconnect them, and cut them out.


How do I know this?

I stopped counting when I passed the 1,000 mark for phones installed. I installed cellphones in everything from junkers that didn't even run (seriously!), to multi-million dollar yachts.

I even installed a few in Cherokees!
