I have a quick question about exactly what parts I need to order to get my gun up and running. So here's the deal:
I recently purchased a used KM4 RIS from a guy for a real good price. The only catch is, it was a "Shoe Box Gun" meaning It was in pieces, and said pieces were in a shoe box.

Anyway, all the parts are there except for the electricals. I need a completely new trigger switch assembly as well as the crane stock wiring harness. I know what to get as far as the wiring harness:(
This), but not sure about the trigger switch. I was wondering if
This is what I need. Does it come with all the wiring and connectors and everything. And if all the wiring/connectors are included, are they already soldered on/wired to the rear? Or would I have to do the soldering my self?
I basically want a KWA factory parts version of something like
This.
So can I get something like that from the pro shop? With the wires connected/soldered and ready to be "dropped in"? Or would i have to solder them on my self? Or am I just out of luck?
