Fitting mosfet to JG MAC10. Where to solder trigger contact wires?

[CzechMeOut]

I have a Jefftron Micro mosfet I want to fit to my JG MAC10.

Could anyone point me to where the trigger contact wires should be soldered to?

Also I'm OK to get rid of the original fuse as the mosfet will replace it's function correct?

Thanks!
