Default TK-22 and my first electrical fire

So.

I have a HL JagdPanther which I've been slowly trying to upgrade. The next step was to install a TK-22 on it as I wanted to replace the Tx with a 2.4GHz system. Previously when I tried to install it, the tank didn't respond at all: no engine start/sound, no movement, nothing. So I thought it was the Tx I got. I rigged a battery case and a separate micro servo separately to test it and maybe rebind it. Did all of it, servo was responsive on all 6 channels. So at this point it's not the Tx/Rx.

I installed it again and again no response, as if no power was going to the TK-22. Then I remembered (and looked it up again) that I had to put a jumper or the smoker switch plug to the SW port on the TK-22. So I unplugged the smoker switch from its own socket and plugged it there. No go. Then I remembered ok maybe I need to turn the smoker switch ON. I did that, made sure battery switch was on as well (yes this was plugged to CN1 or the battery port on the TK). Again nothing. I pulled up my reference video again and in the middle of watching it, smoke started to come out of my tank!

The wires from the battery to the TK-22 started melting and smoke was coming out, and I think a little fire even spewed up from the wires. I quickly turned off everything I can and unplugged the battery cable from the TK-22, then the rest of the cables. I ran with the tank outside in the backyard as the smoke wasn't stopping. I then just cut the wires from the battery.

So what did I do wrong?

And what happened?

I know I messed up somewhere and not that upset about the whole ordeal (wife was however). I just want to learn from it and actually install the TK-22 (it's been sitting on my work area for a few weeks now) properly.

I'd like to know what my options are. And if FreakyDude is reading this, need some advice. I would maybe want to send the unit back to you and see if there's something wrong with it? Not looking for a replacement or refund unless it was really a defective unit I just want to know if I fried it (the unit didn't seem hot or components smoked or burned in fact it still looked like no power was going to it) or if it's salvageable. At this point I'm very apprehensive about plugging this to another HL of mine (for obvious reasons).

Here are my references when I was trying to install the TK-22:

Come to think of it, any advice from anyone would be helpful.
