Can't really tell from your picture.
Type 1 vs Type 2 cables, you look to have all type 2 cables (no difference other than for replacement gun shells and cables, you normally see a little metal on the bottom of the gun for Type 1).
Type 1 vs Type 2 gun I/O pcb, you'll have to open them up for that. Both work ok. Type 1 is more through hole soldering and Type 2 is more surface mount. The newer type 2 is supposed to do better when dropped too.
I can't tell, but if you have more than 4 wires, they will also have recoil in them. Which, may or may not work. Normally it is 24v.
