AC fuse keeps blowing

Every time I turn on the AC the fuse blows instantly. Worked perfectly last season.... brrrrrr.

Late last fall I installed a new:radiator, new transmission lines and timing belt, water pump, etc. I needed to remove ac pump and swing to the side. No hoses disconnected but the wire harness needed to be unplugged. I rechecked the plug a few weeks ago and I had not pushed it together completely. So I did and thought "oh good, a simple fix!" NOT!

 

Did you ever find a solution? I put in new 7.5a fuse and it blows immediately. The digital dash doesn't turn on and I can't roll my windows up or down. The first time this happened Toyota found out that a security system wasn't properly removed. (I bought the car used.) That fixed it for about a year. Then I had my oil changed and now its doing it again.

 

Oh man, sorry mine is a 2015 Toyota Tundra Limited.
