You'll use the three JST PH 3-Pin ports on the FunHouse to control the ultrasonic distance sensor and the NeoPixel strip.
The distance sensor uses power, ground, a digital output (to control pings), and a digital input (to read the signal). You can wire these four connections by using two of the JST ports.
Prep two of the cables by removing the ground from one and the power from the other as shown. Pry up the plastic tab holding the crimp connector and then slide the wire out of the housing.
Alternately, you can simply leave the extra two wires in place and simple insulate their ends to prevent accidental shorting.
You can plug the sensor into the JST cables directly, or use extension cables to connect the JST wires to the ultrasonic sensor as shown here:
