Check engine light after pulling wiring harness

[nichos]

Hi all, I wired up my dashcam a while ago, and pulled the wiring harness (big blue thing, see picture below). When I started the truck up it had a check engine light on (CEL). After a while it went away, I figured I unplugged a sensor or something.

 

Fast forward to 2 days ago I repeated the process for attaching my CB and sure enough, the CEL came on. However, this time it's not going away.

 

It's been over a 100 miles, at least 10 starts and stops. I've unplugged the battery for 2 hours, and also cleared the code using an old scanner I had, and the light came back.

 

Does anyone have any suggestions?

Autozone says it's codes: p305c and p305e

So after doing some digging, I found out that the code says the wiring harness is loose. I inspected it, and the red tab is bent. Does anyone know the part number for the blue harness in the picture above? I'm afraid to see how much it costs, but I think that's my solution.

What part is actually damage? The red part in the photo is just the secondary lock to keep the lever from being opened to disengage the connector. Unless the lever is moving that is not the cause of your issue. Is the connector properly seated? Did any pins get bent? What wires did you connect to?

I plan on running to that same box and there's a open slot with switched and one with constant, so don't need to even pull that blue part off anyway
