D104 on a TYT TH-9800

Got this new radio and found there was little to no information on the pin assignments. I found this which was flipped. I had given up until almost midnight I thought what if this guys diagram is backwards. So I tested 4 for ground and there wasn't. Then I tested 3 for ground and there was. So I touched 3 and 1 together and click it was transmitting. So a quick wiring job with a RJ11 and a couple of keystones and boom it was working. 

The RJ11/12 you are looking from the back of the plug and pin 1 is on the left. 

Addendum: Older models are flipped so the wiring will look like this.
