Wires for TRS Jack
We'll need two wires to connect the TRS Jack. These should be about 4 inches in length. Just like our previous wires, using wire strippers, remove a bit of insulation from the tips of each wire and add a bit of solder to tin them.
Wiring TRS Jack
Two of the three leads on the jack will need to be bridged together in order to properly connect to AT switches. Insert a wire through the hole of one lead and thread it through another.
Solder Ring to Tip
We'll use a bit of solder to connect the wire to both leads on the jack. A bit of extra wire may be helpful. Try keeping the jack stable while soldering. Holding the wire with third helping hands might also be helpful.
Solder Wire to Sleeve
Now we can attach the second wire to the remaining lead on jack using a bit of solder.
Check Solder Joints
Thoroughly inspect the solder joints and see if they're solid. Double check the leads to ensure the correct ones are bridging.
TRS Jack to VERTER
Connect one of the wires from the jack to the positive pin on VERTER. I'm using the secondary pin on the voltage output. This pin arrangement is typically for USB.
Connect TRS Jack to Motor
Now we can connect the second wire on to the jack to the motor. This wire will need to share a connection with the lead that has a wire connecting to the arcade button. Soldering to the existing lead might cause the first wire to come loose so you might need to hold on to both of them while soldering.
Test TRS Jack Circuit
With everything wired up now we can test out the circuit. The LED should light up and motor spin when pressing the button. To test the jack, you can connect a regular pair of headphones or 1/8 audio cable and see if that makes the motor spin. If everything is good, we start putting it in the enclosure!
