Step 6Wire Up Stick Connector
The Sanwa stick installed in the HRAP2 uses a 5 pin connector that is already in place. We're going to use it as well.
Starting at the stick connector, separate the 5 wires going to the stick from the rest of the bundle. Set the rest of the wires through the hole in the control panel to keep them out of the way.
Check the length of the wires from the stick. We want them pretty close to the same length. Trim however much is necessary for them to be within 1/2" of each other. Strip about 1/4" of insulation off of the end of each of these 5 wires.
For this step, you will need a 6 pin Molex KK connector, and the crimp pins to go with it. Looking at the crimp pins, there are two places we'll be crimping: a smaller section in the middle of the pin, and the longer tabs on the end. We'll start with the middle. Place the wire into the groove of the pin, with the insulation ending between the two crimp points. Use a pair of needle nose pliers (or a proper Molex crimping tool if you're rich) to bend and squeeze each of the two flaps over the wire in turn. You don't want to have them just bend in half and go flat; you want them to wrap around the wire and each other. If you take a peek at the connector itself, we'll have to push these pins into a very little hole, so get the wire gripped securely, wrapped as tight as you can. When both are folded in place squish them down hard with the pliers. Repeat the same process with the larger flaps over the insulation of the wire. Getting the larger flaps to cooperate with such small wire can be a pain. If needed, you can clip ONE, and only one, of the flaps to make it shorter.Fold that flat around the wire first, and wrap the longer flap all of the way around over it. Press hard with the pliers to secure it. Repeat for all five wires.
Now all five wires are ready to be inserted. Before inserting the pins, take a moment to verify you know where they should be going.
The six pin stick connector is labeled for each pin: V G D U R L, for VCC, Ground, Down, Up, Right, and Left. Go ahead and insert the plastic connector on the header to make sure you have the orientation the right way; the connector is keyed to only go on one way.
Next, let's identify what each of the wires coming from the joystick are. Check the wiring diagram below and compare it to how the harness is oriented in your stick. It probably matches the second picture, with the pins of the harness pointing at the buttons. The order of the colored wires should match those in the picture; compare to make sure. If they aren't, then write down the color of the wire, and the function it plays according to the order in the harness. You need to know which pin goes to which direction and ground.
In my case, the order of the wires and the orientation of the Sanwa PCB match the second image, which tells us:
Black - Ground
Green - Left
Yellow - Right
Orange - Down
Red - Up
If you want to take a moment to test it out, use a multimeter. The connection between each direction and ground should show low resistance when the matching direction is pressed.
Now that we know the function of each wire, we can start inserting them into the Molex connector. The pin marked 'V' on the UPCB won't be used, since the stick doesn't require power. Start inserting each pin into the appropriate spot on the molex connector. When it is inserted all of the way, you should hear a little 'click' as it locks in place.
Once all five wires are installed, bundle up the stick wires with a few zip ties to keep them together and looking nice.
