Wiring Harness

I started cleaning up my engine and engine compartment today. The engine was changed out to carb. The person I bought the car from did all kind of wiring, MSD, push button start toggle switch for fuel pump, ignition and everything else. I want to remove the wiring harness because right now, there are wires and plugs tucked and zipped stripped everywhere. What's the easiest way to go about removing all the excess wires and plugs? I'm thinking I should be able to just unplugg it, but ofcourse I still need lights, door locks, window controls etc. Any suggestions?

What a butchered mess.
It would be kinda tough to instruct you what to leave and what to cut over the internet.
Seeing that you have eliminated the computer and the need for the related wiring,It would look nice to tidy up a bit under there.
At this point I think you should find a guy who is good at automotive electrical and see if he wants the work.
I am not trying to be insulting here so dont get me wrong.
I am almost done with a similar type of project on a 90 Dakota...went from efi to carb, different alternator,mallory Ignition, all with the factory gauges.
It has taken quite a few hours to extract the efi harness, leaving only necessary wiring, adding the correct wiring for the now not computer controlled charging system, wiring the A518 to have overdrive function properly controlled,an ignition run and bypass circuit for the new ignition system, and I am still looking for info about the factory tach and how to interface it to keep a factory appearance in the interior.
I have poured over the wiring schematic for quite a few hours and pulled wires and cut wires and spliced and soldered wires and......
Point is It could wind up being too much of a challenge and only serve to sicken you of the project.
If you still want to tackle it, I would be glad to answer some questions and coach you on how to wire it. You will want to get a complete wiring schematic for the car and learn how to read it.

looks like a late 80s to mid nineties ford mustang, just by looking at the shortie headers.

Re

Sorry about that. It's a '88 Mustang GT, 5-speed manual. I found a post that told me exactly what I needed to know. It explains the EEC harness and the main or "chassis" harness. The EEC harness contains all of the computer related sensors, actuators, and such. It also contains some of the wiring for the air bag system. The chassis harness contains everything else; headlights, fuel pump wiring, instrument cluster, etc., etc. Thanks for the replies.
