SVD Build: What do I solder the signal wire to?

[Morcovul Raul]

Hi all, 

New to the forum and looking for some advice.

I won a CYMA SVD a year ago at Proving Grounds, but it was not new and in terrible shape.  Just doing the basic starter upgrades got it up to 299fps consistently, and I have since been meaning to go back in and sort the internals out properly - heavier gauge wire, spring, piston, nozzle, &c. - and I bought an FPS micro mosfet but I do not know where I should attach the signal wire?

Any help with that would be greatly appreciated.

 

TIA.

Red wire goes to 1 pole on the trigger along with the red wire from the motor. signal wire goes on the other pole of the trigger. motor Black wire goes to the mosfet and then to the battery

Thanks Mightjebus!

You are truly worthy of your name, and I shall give that a bash.
