Was this a new harness or did you get it out of another vehicle?
If this was a new harness, then I suspect you have a connector that is not fully connected.
Take a look at all the info below for these codes and you will see that they are all circuit codes which means we are going to have to start with checking the connections of the harness that you installed and any others that you may have disconnected.
The next thing is we are going to have to start running through testing the wiring for opens or other wiring issues with the actual harness.

Clearly if these codes were not there before then this issue is related to this harness, so we are going to have to start with this.
