Tail Lights, license plate lights, and OEM trailer socket blows fuse

Will do.

 

Without replacing green wire on 1D; De-pin on 1C, resulted in same fuse blowing when lights turned on.

 

Bummer, thought that exterior circuits were the culprit. The remaining internal ones are difficult to de-pin.

 

Next:

Still keeping removed pins out...

 

This 7 & 19 pins in connector 1J provide juice to dash switches, radio, a/c, etc.(illumination circuit)

 

This is headed in the direction I was thinking it might be. The ac module is fairly easy to pull out and might be worth unplugging the connector to see if that eliminates the problem. Looks like your doing a tremendous job following caribe makaira’s Directions. He’s posted advise on here before and is very knowledgeable. Definitely a great resource. Good luck!

 

Rodent problem? Unless this has always been an issue I'd be looking for something that has changed.

 

Update.
First, thanks to all who helped me. I learned a great deal going through this process.
I figured out the short. I forgot I had made a single mod five years ago when I first bought the truck. I had tapped into the green wires adjacent to the gear shift, and added a couple of LEDs under the seat and the gear shift.
As soon as I disconnected those wires, the fuse stopped blowing.
All the other lights are now working, except the passenger parking light, which I'm assuming I didnt repin correctly, so I'll complete that and put it all back together.
Regardless of how knucklehead it was with regard to forgetting about the LEDs I added 5 years ago, the education was worth it.
Again, thanks.

 

Thanks for all the help.

What do you think the Stealship shop would've done?

 

Hundreds

 

I meant in job, I've seen over here that they remove harness and replace with new ones until they get to the "issue" then the bill is as you say hundreds...anyhow , glad you got it.

 

what was the mod you did? I’m currently having the same exact problem with the tail light fuse blowing. I have done a few mods, one being the abs shut off and the other is the always on fog light mod. Maybe this is my problem... also my passenger side parking light has been out for almost a year now and I could never figure that out either. Let me know if you ever solved that problem too
