So I'm no mechanic but it applies to a standard also right? Just making sure because i got cut wires right there and I don't know what's going on in the car. It's actually my first car i ever owned. Just got it so trying to figure out the problems with it now, and how bad is this for the car because it runs and drives.

If you have a manual transmission, you do not need a SDU. The DDCT is an automatic. Someone has done a transmission swap. Good that it's a manual now because the DDCT is the worst automatic transmission possible in a Dart. You probably have all kinds of codes and messages on the cluster if the swap was done without the electronics. Get a scan and post the codes so we can figure out if any of it is a problem.

Get a build sheet done using your VIN to see what options your Dart had from the factory.

People with a DDCT often ask if they can swap in a manual transmission. Let us know what you find. I'm curious if it's even possible considering how all the modules are married to each other by VIN.

Turns out it was a standard so they must have switched the harness in the car then to even have the wires and my battery box must have come out of a auto too because the mounting spot for the DDCT thing is there.So now just to get my O2 sensors working and I should be OK because everything else seems to work fine.

Do you know where my upper O2 sensors plug in at? I can't find the plugin for the computer.

The upstream O2 sensor connector is #1 in this pic (downstream is #2)

If you are asking where to connect a scanner. the DLC connector is just under the left side of the panel below the steering wheel. I don't have a good pic for a Dart but it's the same location for just about any car. Here is the DLC for a Neon.

looking if the 2 o2 sensor plugs and the plug for the transmission are all in the same brake off point of the harness for a 6speed 1.4l

If you are trying to identify connectors, use the Mopar connector site:
Wire colors and pinouts should help.

When you figure out what wiring is missing and find that you need to splice wires, there is a correct way. Solder and adhesive lined heat shrink tubing over the splice is the only way the splices will last with engine vibration and heat. Here are a couple links:
